Is there an app (backup or otherwise), that will syncronize a data partition, either on a regular basis, or realtime?
Thanks.
I use “rsync” for that.
When you say “partition” do you really mean partition (sequence of disk blocks with arbitrary unknown format) or you do really mean “content of a filesystem on disk partition”? Both can be synchronized but that requires entirely different tools.
Probably either/or whichever is the least intrusive/quickest/most reliable and easiest to setup for syncing. Initially it will prob be a clone of the partition, and then to keep synced.
Cloning is generally more complicated than using rsync, which is essentially made for the task of replicating filesystem content during normal system operations, rather than booting specially or umounting and remounting a filesystem to be cloned.
rsync is good for one way sync (backup)
If you need two way sync, you can use unison
