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!
It’d be worth checking out Borg as an alternative to rsync. Borg will handle snapshotting, and automatically de-dupe on a block-by-block basis.
I use it for all of my remote backups, and it provides a lot of quality of life stuff that rsync isn’t going to handle.
So for this, would i make another zfs pool on my remote backup server that is not snapshotted? Like, the problem i have is that i have snapshotting via rsync, but then the whole remote server zfs pool is further snapshotted so there’s a lot of redundancy.
