Hey all, i would like to get some feedback on my backup strategy.
I have a debian webserver with a ZFS pool running nextcloud aio, immich and jellyfin. Thinking about adding other services as well but nextcloud and immich are the most important ones. The docker volumes of these services point of course to the zfs pool. My backup strategy would now be to use the internal backup solutions for nextcloud and immich to backup their databases, then stop the docker containers and do a borg backup of the zfs pool. The backups would be stored an extern hard drive (I want to expand on this but for now this is all I can afford). is this a viable approach or do i miss something? Could there be problems in case of a backup with the databases etc? The docker compose files are also stored on another machines together with my server documentation.
Seems pretty plausible, not 3-2-1 yet, but on the way, and should get the habits established well enough. Just having an offline backup is a huge step up from most. Consider a waterproof box (perhaps buried) in the back yard instead of just another room (in case of fire / flood).
If you have a friend with a similar setup, or who perhaps wants one, you can sync over internet and both get your offsite without the expense of online backups or the inconvenience of lugging HDDs around.
