I didn't see anybody talk about incremental backup (the backup
consists of current versions as well as earlier ones -- often earlier
work can replace erroneous or lost current work. Or work you don't
notice is gone for a few days.). There are 2 I know of, and one (and
probably many more) that may do that:
Having been there and done that, I can assure you that having a
live snapshot system -- rsnapshot or btrfs/zfs native tools --
is more fun and less work for everyone.

Only if they do versioning. Otherwise, live snapshots mirror deletes - not very useful if you want to restore an accidental delete!
