![]() These are basically the same as Time Machine snapshots. On top of that, for APFS volumes, CCC now also supports Snapshots. So if you edited a file 6 days in a row and ran a CCC clone every day, there are now 6 versions of that file in SafetyNet that you can pull out and restore, similar to Time Machine.Ĭhronosync has a similar feature, but they call it Archives. For a while now CCC has had SafetyNet, which preserves items replaced during a backup by moving them to a dedicated folder, and continues to do so with each subsequent backup, by creating dated folders over time (see Ed’s screen shot), as long as there is room on the backup volume. Another thing Chronosync does that the other two don’t is do bidirectional syncing.Ĭlick to expand.Ed beat me to it, and provided a clear illustration of it. A big reason to use Chronosync over the other two is if you want to preview which files will get changed/deleted on the backup (Trial Sync), and have the option to exclude specific files from the sync. It has scheduling, and limited versioning (Archives). But with more of an emphasis on folder-to-folder synchronization (hence the name), even though it can also be used for whole volume bootable backups. Carbon Copy Cloner can be scheduled if you want it to be more automatic like Time Machine, has some power-user options for verification, and limited abilities to clone folders, and to keep versions (using Snapshots).Ĭhronosync is like Carbon Copy Cloner, a backup program for power users. In this way, CCC complements Time Machine neither can fully replace the other. I use this to maintain an exact ready-to-go backup of my entire Mac system, because it takes a while for Time Machine to rebuild one from its backups. If your Time Machine volume runs out of space, the oldest backups are thrown out.Ĭarbon Copy Cloner is primarily designed to create a complete bootable copy (clone) of a Mac system. You can easily recover any backed up versions of specific files and folders, or you can recover an entire bootable Mac (by rebooting into macOS Recovery Mode).
