@nobodyinperson@fosstodon.org @Atemu@darmstadt.social I'm in the process of doing the same, I've just converted a ext4 to #btrfs to do that. I pretty sure that a disk snapshot is suffisant (and i'll go with it). at work we can't/don't stop the service during backup (rsync+#borg). we do have another bckup strategy for postgresql backup (#pgbackrest).

for #selfhosting, it will be enough,i'm confident that my service can endure a powercut, so snapshot will be fine.

i haven't figured out how i will manage off-site backup, maybe export a tar from borg ? or rsync the repo even if it's not advised.
