Carbon Copy Cloner backups are better than ordinary backups. Suppose the unthinkable happens while you’re under deadline to finish a project: your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. With ordinary backups, you’d spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data.
With Carbon Copy Cloner, your data and the operating system’s data are all preserved on a bootable volume, ready for production at a moment’s notice. When disaster strikes, simply boot from your backup and get back to using your Mac. At your convenience, replace the failed hard drive and then let CCC restore the OS, your data and your settings directly from the backup in one easy step.
Any backup application can save your stuff. A CCC bootable backup will save your productivity too!
- Authentication errors that occur when failing to mount the destination Data volume are now handled correctly (i.e. you'll get a "Reset Password" prompt instead of a generic error).
- CCC no longer avoids rebuilding the dynamic linker shared cache on Macs with less than 4GB of RAM. We found that this resolved system performance issues in the past, but now it only exacerbates system performance issues on these anemic systems when running macOS Catalina.
- CCC will now disallow the conversion of an HFS+ formatted Drobo volume to APFS because Drobo does not currently support APFS. This does not prevent you from reformatting a Drobo volume yourself and selecting it as a destination for a Catalina bootable backup, but CCC is no longer going to perform the task that places the Drobo volume in an unsupported configuration. If you want to use your Drobo device as a bootable backup, you should share that feedback with Drobo.
- Added a "Reveal Data Volume" button to the source and destination selector when the applicable volume is a mounted System volume.
- Catalina: CCC's Cloning Coach now warns that a FireWire-attached destination is not bootable on Catalina+ (Apple no longer supports this configuration).
- Catalina: Errors encountered during the System volume backup will no longer cause the Data volume backup to fail, and the errors are now presented with more helpful advice.
- High Sierra+: Fixed an issue that resulted in non-bootable clones when specifying a volume other than the current startup disk as the source.
- The task selection in CCC's sidebar is retained more reliably.
- Fixed a logic issue that caused CCC's restart or shutdown requests to fail when no user is logged in.
- Catalina: Addressed a issue where an "On reconnect" task would fail to run when the destination volume was reconnected in cases where the source is the startup disk and the System volume had been replaced entirely during a system software update.
- CCC now works around volume unmount interference caused by CleanMyDrive. That product can still cause trouble for Disk Utility, however, so consider disabling that software if you're having trouble with an HFS+-to-APFS conversion, for example.
- Addressed an issue in which the source and destination selections might not be cleared out in Simple Mode.
- Fixed an issue in which CCC would report that it was unable to collect the details about the underlying volume when selecting a folder on a volume within a volume group, and when that underlying volume's name had a non-ASCII character (e.g. "CCC Backup - Données").
