CCC can (and currently does by default, I believe) use a "Safety Net"
feature that moves changed files to dated subdirectories of "/_CCC
Archives/" before replacing them. It can also be configured to pre-clear
old archive directories to make space for new backups.
An advantage TM has is (usually) very fast determination of what needs
to be backed up via the FSEvents API, while CCC always takes about the
same long time to scan the whole disk and compare it to the last backup.
