What's new in this version: Carbon Copy Cloner 5.1.1 Build 5406
- Change log not available for this version
Carbon Copy Cloner 5.1.0 Build 5389
- Added support for creating a snapshot on an APFS-formatted source at the beginning of the backup task. This snapshot is then mounted and used as the source for copying files. By using a read-only volume as the source, we avoid rare, but potential conflicts that can occur during the backup task if files are modified while being copied
- CCC's SafetyNet feature is now built on top of APFS snapshots when the destination is an APFS volume and snapshot support is enabled for that volume
- CCC will create a snapshot on APFS destination volumes at the end of a backup task to establish a point-in-time restore point
- CCC offers a highly-tunable snapshot retention policy that allows you to define how long snapshots will be retained (hourly, daily, weekly), and also allows you to define a minimum amount of free space to retain on the volume
- CCC's Disk Center offers detailed insight into the snapshots that CCC and Time Machine have created on your APFS volumes. Quickly see how much space those snapshots are consuming, and delete one or many snapshots with the press of a button

Carbon Copy Cloner 5.0.9 Build 5266
- This update implements a workaround for a serious flaw that we've discovered in macOS that can lead to data loss when using an APFS-formatted disk image. If you're running macOS High Sierra, please apply this update and review any tasks that back up to a disk image on a network volume. Note: this flaw applies to APFS disk images only — ordinary APFS volumes (e.g. your SSD startup disk) are not affected. Disk images are not used for most backup task activity, they are generally only applicable when making backups to network volumes
Carbon Copy Cloner 5.0.8 Build 5263
- Fixed an issue introduced in CCC 5.0.6 in which CCC was mishandling the encoding of a network volume whose username or hostname contained special characters (e.g. "some user@Airport Base Station.local"). That led to errors mounting the affected network volume during an automated backup task
- Errors related to creating a Recovery HD archive are now suppressed if those errors are the result of the user stopping the backup task while CCC was creating the Recovery HD archive
Carbon Copy Cloner 5.0.7 Build 5254
- Fixed an issue introduced by 5.0.6 in which CCC was mishandling the encoding of a network volume whose hostname contained special characters (e.g. "Airport Base Station.local"). That led to errors mounting the affected network volume during an automated backup task
Carbon Copy Cloner 5.0.6 Build 5245
- We made some improvements to the postflight option that unmounts the destination volume. If the destination is an encrypted volume, the volume will now be immediately locked when unmounted (negating the need for a separate postflight script as referenced in our blog). If the destination is an ordinary volume and the only partition on an external device, the destination device should be more likely to spin down the disk
- Improved the efficiency of copying sparse files on APFS volumes. Sparse files appear larger than the amount of data they actually contain. In the wild, we've seen sparse files used by VMWare
- Notifications prompting you to reattach a missing source/destination will now be revoked when the task starts to run next (e.g. when you attach the missing disk)
- Fixed a subtle timing issue that occurs when a scheduled task with an hourly run time limit starts a couple seconds early. A task with such a limit would previously have stopped immediately, claiming that it was running outside of its allowed time window
- The remote Macintosh option now handles IPv6 addresses more gracefully
- Addressed an edge-case scenario in which CCC would set overly-restrictive ownership/permissions settings on the destination root folder
- The Task Filter window now correctly shows the application of a system items exclusion filter when the destination is a NAS volume that is not currently mounted
- Fixed a behavior problem in the Task Filter window that arose after refreshing the size of a folder that had excluded items
Carbon Copy Cloner 5.0.5 Build 5213
- Fixed a scheduling issue in which tasks would not be scheduled for the original start time hour (in local time) after a time zone switch and a restart
- Progress indication during a "Backup with Health Check" is no longer errantly indeterminate
- Addressed an issue that was introduced by the 10.13.2 update which causes Remote Macintosh setup to fail with an internal error
- Fixed an issue in which CCC was unable to mount the source for an HFS+ Recovery HD cloning task
- Custom port numbers are now supported for AFP and SMB hosts
- The task outlook table now correctly displays the run times for tasks configured to run weekly with a repeat interval greater than 1
- Fixed an issue in which some tasks were getting errantly marked with a "task failed" badge
- Clicking on a task finished notification will now open the CCC application and select the relevant task
- Fixed an issue in which a backup task involving a remote Mac would stall if the source or destination volume on the remote Mac was not available
- ZFS volume mount notifications are now handled more effectively
- The CCC command line application will now exit immediately after starting a task group
- Made some minor improvements to CCC's task database that should make it more resilient to corruption
- Fixed a minor window sizing issue specific to Yosemite and the dialog that is produced when disabling the SafetyNet setting
- Suppressed an errant error message produced by High Sierra that can occur when converting a sparse disk image to a read-only format
Carbon Copy Cloner 5.0.4 Build 5163
- Fixed the resolution of the task badge on Retina displays on High Sierra
- When creating a disk image, the disk image is now formatted as APFS if the source is an APFS volume. CCC also creates the Preboot and Recovery volumes on these disk images so that they can be restored using Disk Utility (in addition to being restorable via CCC)
- Items marked as hidden now stay reliably hidden on an HFS+ destination on High Sierra
- Addressed an issue in which a task that specifies a remote Macintosh as the source or destination would re-try the connection too aggressively if the remote host was unavailable
- Fixed the free space indicator for APFS volumes when viewing a volume's details in CCC's sidebar
- Implemented an alternative key installation method for cases where the remote Macintosh cannot accept files via scp
- Improved the drawing of the task outlook table when viewing a task group
- Minor enhancements to the CCC command-line utility
- The source/destination contextual menu items now more consistently refer to the underlying volume for a disk image, and mounting/unmounting the underlying network volume for a disk image now works. Also tweaked the subtitle offered when an underlying network volume is not mounted. Previously it said '"{sharepoint}" is missing', now it says '"{sharepoint}" is not mounted'
- The "Show Details" button in CCC notifications that are presented as alerts now correctly opens the Task History event in CCC
- CCC now handles an undocumented Keychain Services error code that was occurring when CCC was trying to open its keychain for the first time (i.e. before the keychain yet exists). This resolves an issue that some High Sierra users might have encountered when trying to save a password to CCC's keychain
- Addressed an issue in which a backup task could stall while "Cleaning up" if the task was configured to unmount the destination volume, and Spotlight was dissenting the volume unmount
- Minor improvements to the Task Trend chart in the Task History window
Carbon Copy Cloner 5.0.3 Build 5121
- Change log not available for this version
Carbon Copy Cloner 5.0.3 Build 5115
- Addressed an issue in which task history events weren't getting recorded for a subset of backup tasks
- Improved the performance of CCC's archive pruning utility
- Fixed an issue in which CCC may not have presented a dialog to update the HFS+ Recovery HD volume on the destination when the source is an APFS volume
- Fixed a window resizing issue affecting the "New disk image" Save panel for High Sierra users
- Fixed issue affecting Yosemite users in which custom filters in the Task Filter window were hidden despite the custom filter table being shown
- Fixed an issue in which the setting to skip weekend days was getting disabled for tasks configured to run on a daily or weekly basis
Carbon Copy Cloner 5.0.2 Build 5103
- Added a menu option to clear CCC's entire Task History
- Added Stop Loading, Reload, Make Text Larger, and Make Text Smaller buttons to the Documentation tab of CCC's Help window
- Added a couple more ways to rename tasks and groups, because a lot of people were having trouble with this. Previously the semantics were similar to that of the Finder, e.g. click on the text of the title, or select the task and press the Return key to make the text editable. Now you can double-click a task in the task list to make the title text editable, or you can right-click on the text and choose the option to rename the task
- Tasks listed in the CCC menubar application are now sorted in the same manner as defined in the Tasks table of the main application. The same is now true for the View menu in the main application
- The run time order for grouped tasks is now considered when sorting the Tasks table by next run time
- Fixed the "failed to set global attribute" error on first launch for upgrading users
- Fixed a bug that could cause a spin if a CCC v4 imported task had been configured to run weekly, only on Sunday, and also with a runtime limit that prevented it from running on weekends
- Fixed a condition in which CCC would report that an error occurred while updating the dynamic linker shared cache and kernel extension cache (it wasn't an error, it was just new debug information)
- Resolved some edge cases that caused remote Macintosh authorization setup to fail
- Connection reset errors (e.g. remote host drops the connection) now cause a remote Mac task to be restarted
- Imported v4 tasks with a remote Mac destination are no longer prevented from copying system items (i.e. because we don't yet know the destination filesystem)
- Fixed an errant cloning coach message that said the destination on a remote Mac wouldn't be bootable because it wasn't the root of a volume
- Fixed the source/destination label in cases where the item is a remote Mac. The label wasn't updating consistently, and sometimes was left at the stub text
- Addressed some cases where CCC would consistently prompt the user for a guided setup when a task with "restore" in its name is present and specifies the current startup disk as the destination, or when the relvant destination volume is named "Macintosh HD"
- Guided Setup and Guided Restore is now disabled if VoiceOver is active. Some VoiceOver users found that these bubble tips were stealing VoiceOver's focus, making task setup more challenging
- Fixed an issue in which CCC would become unresponsive if you configured a daily or weekly task to start at 7AM, and then checked the box to apply an hourly runtime limit
- System files are now excluded if the source has an OS older than 10.13 and the destination is APFS. Added a Cloning Coach message to explain the limitation
- APFS as a system destination is only supported when the running system is 10.13+
- Fixed the abbreviation for "Monday" that was incorrectly translated in German to "Monat" (rather than "Mo")
- Increased the threshold for system uptime at the time of CCC load to 90 for determining whether the system just restarted. This accommodates slower systems that would otherwise skip a task that was missed while the system was off
- Write failures on NAS volumes are now more consistently presented as showstoppers that cause the task to fail rather than individual file errors in an otherwise-successful backup task
- Added some tolerance to the hourly run time limits such that tasks firing a few seconds before the limit window will be allowed to run
- Fixed an issue in which running a task group could lead to an inability to sleep the system
- Tasks that are both disabled and suspended now correctly get the "activate/leave suspended" dialog
- A task can now be moved back outside of a group if there is only one group present and all tasks are part of that group
- Enabled expansion tooltips for the task name in the task outlook table
- Fixed an issue in which the destination APFS Preboot volume was not getting properly populated when using an HFS+ source volume
- The Preferences window is no longer moved to the main screen if its on the secondary screen and the secondary screen is positioned below the main screen
- Improved some dialog behavior for tasks configured to run on source/destination reconnect, that also are configured to prompt before proceeding and issue a periodic reminder. The CCC User Agent now revokes a reminder prompt if you attach the affected disk before dismissing the reminder prompt
- Made some minor modifications to CCC's global exclusions list that resolves a startup delay when booting from the backup volume
- "Delete a SafetyNet folder" now accepts any item that is in the Trash
- The "Auto adjust" setting being disabled will no longer cause the advanced settings view to be expanded if the SafetyNet is set to Off
- Fixed an errant Cloning Coach message that said file metadata would not be preserved on a disk image on a network volume
- Cancelling out of the filter window without making changes will no longer leave the task in the edit state
- System folders are no longer excluded when copying to or from a folder on the startup disk
- Fixed a software update issue in which CCC might check for updates on startup if the update interval was set to never check
- Fixed the calculation of a task's elapsed time as noted in the Task Plan
Carbon Copy Cloner 5.0.2 Build 5102
Fixed:
- An issue introduced in the 5.0.1 update in which backup tasks would errantly report that an error had occurred during archive pruning
- Fixed the "failed to set global attribute" error on first launch for upgrading users

Carbon Copy Cloner 5.0 Build 5039
- CCC's SafetyNet pruning settings will now automatically adapt to the amount of data your tasks need to copy. If a backup task runs out of space on the destination, CCC will revisit the pruning of the SafetyNet folder, then resume copying
- The SafetyNet pruning feature is now available for Remote Macintosh destinations
- The setup procedure for backing up to a remote Macintosh has been greatly simplified
- Task filters can be configured for Remote Macintosh source volumes with the same ease as locally-attached volumes
- Tasks can be sorted by name, exit status, last run date, next run date, or manually
- Tasks cab be placed into groups for organizational purposes, and also to be run collectively as a group
- A new Guided Setup feature offers initial task configuration tips for first-time users
- Upon detecting that your Mac is booted from a CCC backup volume, CCC will present a new Guided Restore option. In the guided restore, CCC will create a new restore task, select the startup disk as the source, then present coaching tips that guide the user through selecting the destination and (optionally) excluding items from the restore task
- Tasks can be scheduled to run once at a particular time in the future. After that run, the tasks will revert to run "only when I click the Clone button"
- Hourly runtime limits allow the user to limit a task to running only between 5PM and 7AM, for example. Hourly limits will prevent a task from starting if it's outside the specified run time, and if the task runs past the allowed end time, the task will be stopped
- CCC's Task History window now offers a trend chart. The trend chart shows how your tasks are performing over time, and how many files/how much data gets copied each time your task runs
- The destination selector offers a visual disk usage indicator
- You can right-click on a volume (e.g. in the source/destination selectors) to mount or unmount that volume, or to reveal it in the Finder
- The source and destination selections can be reset to "Choose a source/destination"
- The CCC User Agent will now check for updates on the schedule defined in the main application
- Some of the the Cloning Coach messages have been aggregated and simplified to seem less daunting to novice users
- The "Find and replace corrupted files" setting can now be limited to run once per week or once per month
- Tasks can be imported and exported, making it simpler to migrate task settings to a second Mac
New interface for defining task filters:
- CCC can calculate the amount of space consumed by the files on the source. If you exclude items from the task or add custom filters to exclude items based on patterns, CCC will report the total protected size of each folder (and cumulatively)
- The task filter can now exclude everything by default, allowing you to specify only what items should be included in the backup task. This is in contrast to the default behavior in which CCC includes everything by default, allowing you to specify what is excluded from the backup task
- Filters can be imported and exported. Additionally, when you change the source for your backup task, CCC will now ask you whether you want to reset the task filter (rather than simply resetting it)
- The effects of custom and global filters are immediately apparent
- A QuickLook panel shows a preview of the selected file
- Contents can be sorted by name, modification date, or size
- You can select an item, then Shift+click on the checkbox for another item within the same parent folder to select/deselect all of the items in between
- If you really want to, you can have CCC copy your Trash. There's a checkbox for that now
Carbon Copy Cloner 4.1.18 Build 4592
Improved:
- Updating the dynamic linker shared cache is now enabled for macOS 10.13 High Sierra systems that have at least 4GB of RAM; Apple has addressed the issue that led to a watchdog reboot when running this utility, although it still consumes far too much memory to be practical for systems with less than 4GB of RAM
- A "454 temporary failure" error from an SMTP server is now properly handled
Fixed:
- Fixed an issue with resetting the password for an encrypted disk image
- Fixed an issue in which the SIP-related file flags for root-level hidden items on the destination were stripped and not replaced
- Fixed a keychain retrieval bug that occurred when the hostname has a backslash character
Carbon Copy Cloner 4.1.17 Build 4577
- Removed the beta expiration date (~September 5, 2017) that was errantly left in the 4.1.16 production release. Also fixed the issue that allowed that to slip past our release checklist
- Closing a notification that is presented as an alert will no longer cause CCC to open its Task History window on macOS High Sierra
- The disk usage of an APFS volume is now reported correctly when the APFS container has more than one volume
- Fixed a layout issue in the "destructive task warning" dialog
Carbon Copy Cloner 4.1.16 Build 4569
- Change log not available for this version
Carbon Copy Cloner 4.1.16 Build 4564
- Addressed a wake event scheduling issue that was introduced in the 10.12.5 update (yes, we're finding more goodies in that update every week!). CCC normally associates a unique identifier with each wake event that it schedules. That identifier shows that the event was created by CCC and for a specific task. Should CCC need to cancel the wake event (e.g. because you delete the task), CCC looks up the wake event by that unique identifier and deletes it. Starting in 10.12.5, macOS ignores that unique identifier, so now all of the CCC wake events are identical. This led to orphaned wake events getting created. Normally these are harmless and a reboot always removes these, but this update clears them all and uses a new algorithm to identify and remove wake events
- Adds preliminary support for cloning from an APFS startup volume to an HFS+ backup volume (applicable only to macOS High Sierra)
- Fixed an issue in which CCC's scheduled tasks were improperly scheduled when the system clock was set to January 1, 2001 on startup (e.g. in cases where the Mac's motherboard battery is dead)
Carbon Copy Cloner 4.1.15 Build 4549
- Change log not available for this version
Carbon Copy Cloner 4.1.15 Build 4548
- Addressed another bug introduced by the 10.12.5 update that led to a harmless message getting interpreted as an error during the "Rebuilding Kernel Extension Cache" phase of bootable backup tasks
- Minor updates to the Spanish localization of CCC
- Added a "Show Task History" option to the Tasks contextual menu
- When creating a new disk image, CCC now applies more liberal access privileges to the root folder of the new disk image volume. Also corrected a permissions issue that caused startup problems when attempting to boot from a restored disk image
- The Task History window's filter criteria are now cleared when closing the window to avoid having them applied when opening the window in a different context (leading the user to believe that no task events have occurred recently, for example)
Carbon Copy Cloner 4.1.14 Build 4543
- Addressed an issue introduced in an upcoming update to Sierra in which CCC was unable to mount recovery volumes to determine their OS versions
- Improved the sanity check that CCC imposes when responding to a system clock change notification. The previous sanity check that we had imposed was not sufficiently avoiding rescheduling tasks when the system clock was changed to 2040 and then back to a sane time
- Minor improvements to the CCC command-line utility
- Addressed an issue in which CCC would errantly mark tasks as suspended on systems with exceptionally slow startup disks
- Fixed a logic issue that could cause a backup task to appear stalled in the "Creating an archive of the Recovery HD" phase in cases where the source recovery volume could not be unmounted
- Addressed a race condition that could occasionally cause CCC's helper tool to crash upon launch. While this was uncommon, it could occasionally lead to corruption of CCC's keychain if that keychain was getting created upon loading the helper tool
Carbon Copy Cloner 4.1.13 Build 4496
- Addressed an issue in which CCC was unable to save passwords to its keychain after migrating the CCC configuration from another Mac
- Fixed an issue in which CCC would periodically report that a task could not complete due to minor filesystem inconsistencies
- Addressed a Sierra-specific issue in which CCC would not recognize a freshly-created recovery volume due to it being named incorrectly by Disk Utility
- Implemented a workaround for cases where CCC's privileged helper tool is installed but disabled by the system
- We've received a couple reports of Sierra systems errantly setting the date forward to 2040, then immediately back to a sane value just a couple seconds later. Previously CCC would reschedule its tasks forward to 2040 in response to the clock change, but then not backwards to a sane time (because time isn't supposed to go backwards, right?). This version of CCC now implements a sanity check to avoid rescheduling tasks that far into the future
- Fixed an issue in which a scheduled task could resurrect itself if the user deleted it while it was running
- Packet corruption that causes the connection to a remote Mac to be terminated is now handled more gracefully. CCC will now automatically restart the backup task

Carbon Copy Cloner 4.1.10 Build 4424
- CCC 4.1.10 is officially qualified on macOS Sierra. This update includes non-Sierra-specific changes and is recommended for all CCC 4 users.
- Developed a workaround for a bug in macOS Sierra in which FileVault could not be enabled on the destination volume.
- To accommodate changes in macOS Sierra, CCC now creates RSA key pairs for use with the Remote Macintosh option. If you create a new Authentication Credentials Installer Package (ACIP) with this version of CCC, CCC will replace an existing DSA-based key pair on the local Mac. As a result, you must (re)install the ACIP on all remote Macs that you currently have configured in your backup tasks.
- Tasks listed in the postflight task popup menu are now sorted alphabetically.
- Fixed an issue in which creating an empty custom filter would cause the Filters window to misbehave.
- Apple relaxed some restrictions on sparsebundle disk images in macOS Sierra. On these systems, CCC now allows creating and mounting sparsebundle disk images on SMB sharepoints.
- Fixed a logic issue that would cause the "Reset" button to not be displayed when a mounted-disk-image-on-NAS task failed because CCC lacked credentials to mount the underlying NAS volume.
- Recovery HD tasks are prohibited when running on battery power, but this update adds an exception for USB-C MacBooks. For those systems, CCC will explain why the limitation is usually imposed, that an exception is allowed, and that you should take care to not allow the system to sleep for the duration of the Recovery HD creation task. More details on this change are available in the documentation.
- This update to CCC will migrate CCC's keychain file from the user home folder to a global location. Among other issues, this resolves issues where folks couldn't update the password for a NAS volume associated with a particular task if that task was created while logged in to some other user account. That was an esoteric issue that doesn't seem like it should happen a lot, but the number of reports gave us the impetus to address the matter once and for all.
Carbon Copy Cloner 4.1.9 Build 4369
- Change log not available for this version
Carbon Copy Cloner 4.1.9 Build 4365
- If a backup task was configured to back up the startup disk, but the user had excluded system files from the backup task, CCC would avoid recreating startup caches on the destination. CCC logged this uninteresting non-event, but the logging of that event was causing a crash. That crash occurred at the very end of a usually-successful backup task, but resulted in a task history event not being recorded. We fixed that crasher.
- CCC 4.1.8 raises a configuration concern if the destination is a USB device larger than 2TB. This update addresses an issue in which CCC would raise that concern for USB devices larger than 2GB.
- CCC will now unmount (with force, if necessary) the Recovery HD associated with the source volume before attempting to create an archive of that volume. This addresses an issue in which various third-party utilities (especially Antivirus software) would dissent an ordinary unmount request, causing the attempt to archive the Recovery HD to fail.
Carbon Copy Cloner 4.1.8 Build 4360
- CCC will now proactively seek out case conflicts on the destination when the source is a case-sensitive volume and the destination is not. When case conflicts occur in filenames, CCC will append a randomized suffix to the conflicting files on the destination (but all files will be copied). When a case conflict occurs in a folder name, the conflicting folder will not be copied. In every case, CCC will report case conflicts at the end of the backup task and offer advice for resolving the issue.
- Some network volumes incorrectly report themselves as case-insensitive despite being backed by a case-sensitive volume. CCC now tests for case-sensitivity on network volumes rather than trusting the value that is reported in their volume attributes. With this change, CCC can now report potential case-conflict scenarios more consistently to the user when configuring a backup task.
- Made some improvements to SMTP account importing from the Internet Accounts database (El Capitan only). Also added an "Edit" button next to the SMTP account popup menu to make it more obvious how to edit those settings.
- Made some improvements to the presentation of Gmail authentication failures. CCC will now walk the user through the process of creating Gmail app passwords when two-step verification is enabled on the user's Gmail account.
- Added new task history status icons that should be easier to distinguish for users with color vision deficiency.
- Added an "Always show progress window" option to the CCC menubar application menu. That option will always be available now, and closing the mini task progress window will not change that setting.
- Fixed an issue in which the mini task progress window would never be visible if the user had checked the "Hide" button next to CCC User Agent in the Login Items tab of the Users and Groups Preference Pane.
- CCC will now proactively request that the user restore AC power when performing a Recovery HD cloning task. CCC, nor any application, cannot prevent the system from sleeping when running on battery power.
- CCC's privileged helper tool will now dissent a request to unmount a volume if it is currently removing a SafetyNet folder from that volume.
- The free space threshold for deciding whether to compact a sparse disk image is now 25GB or 15% of the capacity of the destination, whichever is larger.
- CCC will wait longer for a preflight disk image compaction task to complete to accommodate slower destination volumes.
- You should never move an application (e.g. from your Downloads folder to the Applications folder) while that application is open. Previously, doing so with CCC could cause it to crash. CCC will now detect if the CCC application file has been moved while CCC is open. If the selected task has unsaved changes, CCC will automatically move the application back to its original location. If that fails, or if there are no unsaved changes, CCC will present a dialog, then quit and reopen itself from the new location.
- Made some improvements to the auto-dismissal of the task finished overlay that's presented within the Task Plan when the selected task has completed. In some cases, that information would be presented, then revoked before the user had a chance to read it. Now it will remain until dismissed.
- The CCC command-line application now has an option to print the task history in CSV format.
- The CCC command-line application can now be invoked to send CCC-badged notifications from a shell script.
- Fixed an issue in which CCC would errantly unmount a FUSE volume at the end of the task if it was mounted with the allow_root flag and mounted by the root user (e.g. with "sudo").
- Addressed an issue in which the reminder associated with tasks configured to run on reconnect could be presented earlier than expected.
- The options to not report an error when the source/destination is missing and to run the task as soon as the missing volume reappears were not previously available to tasks configured to run "Manually when I click the Clone button". That was appropriate, except in one case — when that task was invoked via task chaining. Now those options are made available to manual tasks, but only when those tasks are called via task chaining.
- Added a "Task Configuration" token to the Email Template.
- Improved error handling if errors occur during the attempt to mount a disk image when choosing "Restore from disk image" from CCC's Source selector.
- An exit status of 104 will now cause the global preflight script to cancel the backup task and avoid recording a task history event.
- /.quota.group and /.quota.user are now excluded from the backup task because changing those items on the destination causes the kernel to dissent unmount requests.
- Fixed an issue in which the user could modify a task in CCC, then run the task via the CCC menubar application (which is a separate application from CCC). The task would run with the old settings, though the editor would present UI that suggests that the task is running with the new settings. Now if the user tries to run a task in the edit state via the menubar application, the menubar application will refuse to start the task, present a dialog indicating that the task is being edited, and will then open CCC.
- Fixed a window resizing anomaly that could cause the source selector to be inaccessible.
Carbon Copy Cloner 4.1.7 Build 4285
- Fixed a user interface issue affecting Yosemite users, and only the German, Spanish, and Italian localizations in which the progress bar in the mini progress window would occasionally disappear.
- System items placed in CCC's SafetyNet folder will no longer be impossible to remove when booted from the backup volume (only affects El Capitan users).
- Addressed an issue in which CCC could crash on launch immediately after applying a CCC update.
- Fixed a bug that could cause the backup task to fail with a message asking the user to report the problem.
- Fixed an issue in which the file flags on some system files were not getting preserved when using the "Find and replace corrupted files" option.
- Addressed a scenario in which CCC's email notification would not report the destination volume's stats despite the destination being available during the backup task.
- Fixed an issue in which sparse disk image compaction would fail if the disk image was encrypted.
- Addressed an issue in which CCC would errantly report that it was unable to unmount the destination volume.
- Implemented a better workaround for the DiskArbitration service being unready to mount a just-unlocked CoreStorage volume. Rather than applying a delay before trying to mount the volume, CCC will now attempt to mount the volume immediately (which works in most cases). If that mount attempt fails, CCC will impose a 15 second delay, then attempt to mount the CoreStorage volume again.
Carbon Copy Cloner 4.1.6 Build 4252
New:
- CCC will now attempt to compact a destination sparse disk image if the underlying destination volume has less than 25GB of free space at the beginning of the backup task. This threshold cannot be modified in the user interface (yet), please open a support request if this threshold is too conservative.
Changed:
- Resolved a hang caused by new behavior introduced in the 10.11.1 security update. Starting with 10.11.1, attempting to click on the "Allow" or "Always Allow" buttons when prompted to give access to a keychain item will fail if you are accessing the system via screen sharing. CCC now detects whether the event was initiated via a "virtual click", and in those cases will avoid asking for access to an item in your login keychain.
- When prompting for a NAS volume password, CCC now accepts a blank password (after a confirmation prompt)
- On some El Capitan systems, the disk arbitration service is not ready to mount an encrypted volume immediately after it is unlocked. This build extends the delay that CCC imposes to work around this same bug that was discovered on Yosemite, and has only gotten worse (rdar://18910971 for anyone that has access and influence). Auto-mounting an encrypted destination should work more reliably now.
- The search criteria popup menus in the Task History window are now sorted.
- CCC's User Agent will now revoke Task Started notifications when the corresponding Task Finished notification for that task is sent. This avoids having two notifications per task. Especially for users that prefer to have CCC notifications presented as Alerts, this will reduce some redundancy and free up some screen real estate.
- CCC's user agent is now more proactive about pointing out automated tasks that have been suspended because the system is booted from a different startup disk.
- Applied an exception handler to work around an El Capitan bug that could occasionally lead to crashes on launch.
- Paragon NTFS drivers occasionally add a NULL character to the end of their volume names. This makes it through to the interface as a control character (^@) on Mavericks and is otherwise harmless. On Yosemite, a text view will cause the application to hang if the "NSTextShowsControlCharacters" global default is set. This was an uncommon scenario, so we didn't see this problem frequently. On El Capitan, a text view (i.e. the Task Plan text view) causes a hang whether that global setting is applied or not. The result is that CCC will hang when a task is selected that references a Paragon NTFS volume. This update tediously detects and removes these rogue NULL characters before attempting to display a volume name in the Task Plan.
- CCC will no longer report SoftRAID volumes as "not bootable" due to a partitioning problem.
- Ancillary errors (failures that don't affect data backup, e.g. a failure to send an email notification) are now raised to the user's attention, but in a more subtle manner than for transfer-related errors.
- El Capitan paragraph spacing is almost twice that of Yosemite. Made a small change to how the Task Plan text is formatted on El Capitan to improve the space usage of that text view.
- CCC's scheduled task manager now subscribes to "system clock changed" notifications. If the system clock is automatically adjusted, CCC will now reschedule its task timers to accommodate the change. Normally auto adjustments are made on the scale of a few seconds and those changes are unimportant. We have discovered a few cases, however, where larger changes can occur (unrelated to time zone changes, which are handled differently) that can lead to tasks running much earlier or later than expected.
Fixed
- Fixed a crashing bug introduced in 4.1.5 that would occur when trying to select a folder or disk image on a network volume as the destination to a task.
- If a backup task is configured to unmount the destination volume at the end of the backup task, and Spotlight dissents the unmount request, CCC will unmount the destination with more deliberation to overcome the Spotlight dissent. This change should go a long way towards addressing problems with being unable to eject the destination volume after a backup task runs, an issue that has become especially problemetic on El Capitan due to Spotlight interference.
- El Capitan Finder adds some extended attributes to files while they are being copied by the Finder. In some odd cases, the Finder fails to remove those extended attributes after the copy has completed, and these extended attributes occasionally cause errors when CCC tries to preserve them. CCC no longer tries to preserve these errant extended attributes.
- Fixed a bug that could cause the backup task to fail with a message asking the user to report the problem.
- Added a workaround for enfs filesystem volumes that don't populate the disk arbitration attribute for a volume name, causing them to be named Untitled in CCC's interface.
- addressed an uncommon race condition in which having ccc load on login could lead to two copies of the ccc menubar application being present.
- Improved handling of Keychain write errors when a task is being edited by a user other than the user that created it.
- When looking for Recovery HD sources, CCC will now correctly locate Recovery HD archive files that reside on CoreStorage volumes.

- Task completion notifications offer a bit more granularity on what constitutes "finishing" the task. If a task had more than just transfer errors, we now just say that it failed. This is more appropriate in cases where, for example, the task couldn't proceed at all because the destination was unavailable.

Carbon Copy Cloner 4.1.4 Build 4188
- This update is qualified on OS X El Capitan.
- Fixed an issue that would lead CCC to report that its private keychain is not writable when the keychain had not yet been created.
- CCC will no longer allow running another task as a postflight task if the secondary task is disabled.
- SMTP usernames that contain special characters (e.g. "%") are now accommodated.
- The user agent is no longer re-launched after changing the Show CCC icon in menubar preference. Especially on OS X 10.11, application launch time can be slow and this delay could lead to scenarios in which the preference became out of sync (e.g. if the user were to change that setting very rapidly).
- Addressed a regression in which CCC occasionally could not skip past unreadable files.
- Updated the procedure used to clone the Recovery HD volume to avoid an error at the end of the task that was specific to El Capitan.
- Fixed a UI anomally in which the task name field was difficult to edit when another task was running.
- Fixed an issue in which some UI elements in the Scheduler popover appeared to be disabled (but were not) on Yosemite and El Capitan.
- Fixed an issue in which the "Submit Logs" button in CCC's Help window was inaccessible in non-English localizations.
- Fixed a time zone adjustment issue for cases where a task was created in one time zone but then initially scheduled in another time zone.
- When CCC encounters multiple volumes with the same unique identifier, it now presents the names of those volumes when reporting the problem. This should make it easier to resolve this esoteric issue.
- When disabling the SafetyNet, CCC now asks the user if he would like to delete the SafetyNet folder on the destination. This will help avoid some cases of the task failing due to the destination being full.
- Fixed an issue specific to El Capitan in which debug output spewed by Apple's hdiutil utility would be interpreted as errors and cause a disk image creation or mount task to fail.
- Added custom VoiceOver descriptions for the task status images in the Task History window.
- Added a global exclude for the special hidden .Transporter Library folder. This proprietary device from Connected Data was causing backup tasks to stall due to a bug in the OSXFUSE code that supports that device.
- Fixed an issue in which the reminder timer associated with an "On Reconnect" task wasn't getting removed when the task was switched to ad hoc.
- Added a workaround for fuse4x filesystems that don't advertise support for files larger than 4GB. |
