Automated maintenance of CCC archives |
||
Carbon Copy Cloner will save previous versions of modified files, as well as files deleted since previous backup tasks to an archive folder at the root of the destination. If left unmanaged, this archive folder would eventually consume all free space on your destination volume. To prevent that from happening, CCC offers three different ways of managing the contents of the archives folder. You can customize this behavior by clicking on the "Customize these settings" button in CCC's main window.
Archive pruning occurs at the beginning of a backup task, so CCC will never delete an item that was archived in the current backup task. Additionally, pruning is always limited to the contents of the _CCC Archives folder that is either at the root of the destination, or in the Trash. CCC's pruner won't delete the current versions of files on your destination. Lastly, archive pruning works at a macro level. If any portion of an archive pushes past the limit that you have imposed, the entire archive (e.g. the time-stamped folder) will be pruned.

Automatically prune archived content...
Keep the size of the archive below [xx] (MB/GB)
Starting with the most recent archive, CCC will determine the amount of disk space that each archive consumes. When the cumulative total exceeds the limit that you have imposed, CCC will prune the remaining, older archives. If the newest archive is larger than the limit that you have specified, that archive will be pruned in entirety.
Maintain this much free space [xx] (MB/GB)
If your destination volume has less free space than the limit that you have specified, CCC will prune the oldest archive. CCC will continue to prune the oldest archive until the requested amount of free space has been achieved. Note that if the archives cumulatively consume less space than the limit requested and the destination volume is full, CCC will prune all of the archives.
Prune archives older than [xx] days
CCC will prune archives that were created more than "xx" days ago.
Do not perform automatic pruning
CCC will not automatically prune the contents of the "_CCC Archives" folder at the root of the destination. Archived files may eventually consume all of the free space on the selected destination, so you should periodically delete older archive folders to maintain enough free space for future backups. You may delete the contents of the archives folder without harm to the rest of your backup set.
