Carbon Copy Cloner


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!

What's New Version 5.1.18

  • Addressed an issue that Apple introduced in 10.15.5 (FB7706647) that will prevent CCC from establishing an initial backup of a macOS Catalina system volume
  • Starting in 10.15.5, CCC will no longer back up a macOS Catalina System volume to a disk image destination (i.e. a sparseimage or sparsebundle disk image file). We're making this change reluctantly, unfortunately we just can't get reliable results when using Apple's proprietary utility with disk images
  • Added a green checkmark emoji to the subject of "task completed successfully" emails
  • Improved upon the previous attempts to suppress VirusBarrier attached-but-not-mounted disk images in CCC's sidebar
  • When backing up to a OneDrive or Dropbox folder, CCC will no longer replace online-only placeholder files with a non-placeholder from the source unless the two files' modification dates differ. This resolves an issue in which a user flags a OneDrive/Dropbox folder as "online only" and CCC replaces the placeholders with real files, causing OneDrive/Dropbox to re-upload the content
  • Addressed an issue in which some sparse files were getting copied during every backup. In some cases this led to a noticeable performance degration
