It's World Backup Day again. Good opportunity to check if your backup mechanisms work as intended.

Just have automated incremental backups every few hours

I recently started doing this as well but not sure if it's excessive. I'm beginning to think I need to separate out actual data from ephemeral data (e.g. browser cache, etc)

[–] rice@lemmy.org 1 points 1 year ago (1 children)

If you're doing incremental backups it should be nearly instant if nothing changes. But yea ignoring garbage like cache is always nice

I don't consider it excessive since stuff like rsync -a --inplace --delete on a giant directory will be nearly instant if nothing changed, even with terabytes of data (of smallish files) since it isn't going to copy anything except changed things.

borg used to have an issue where it took forever even with nothing changed but it looks like it is mostly fixed so not an issue now. I moved to restic backup years ago though (which is basically borg without those issues) also proxmox has the proxmox backup server that does similar for all the vps/containers

I have a delta of about 200mb ± which isn't a lot all considered but it changes everyday. The only regular thing I do is use the browser. I might need to exclude it from my incrementals and only do those weekly.

what is a good solution that does incremental backups of docker volumes? o btrfs subvolumes... i have them mapped

[–] rice@lemmy.org 3 points 1 year ago

not sure if there's a docker specific one, I mostly avoid docker. the volumes are accessible by anything as far as I've seen though so anything that does incremental backups (borg, restic, rsync, rsnapshot) should be able to do it there too?
