I currently have two computers, one that has a big zfs raidz pool that I currently back everything up to. Right now, on my local computer I use rsnapshot to do snapshot backups via rsync to the remote zfs pool. I know I’m wasting a ton of space because I have snapshotting in the rsync backup, and then the zfs pool is snapshotted every day.
Does it make sense to just do a regular rsync into a backup directory on the zfs pool and then just rely on the zfs pool snapshotting for snapshotting?
Maybe eventually I will put the local machine on zfs and then just send the local zfs snapshots over, but that will take some time. Thanks!
Have you tried a restore? A non-differential smap snapshot should be fine, but differential snapshots would make a restore difficult to impossible.
A zfssend and zfsrestore with a differential snapshot would be more traditional. If one put mbuffer in the middle, it would even be fast.
