Same story, Hetzner storage box, local backups and at times a backup to my Android phone. Automated backup testing and a notification on Telegram if anything is amiss.

Since you mention it, I am seizing the opportunity to ask: how should borg backup be tested ? Can it be automated ?

It's actually pretty simple using the check command [0]!

  borg check --verify-data REPOSITORY_OR_ARCHIVE

You can add that to a cron job.

Alternatively, I think the Vorta GUI also has a way to easily schedule it[1].

I'll add that one thing I like to do once in a blue-moon is to spin-up a VM and try to recover a few random files. While the check command checks that the data is there and theoretically recoverable, nothing really beats proving to yourself that you can, in a clean environment, recover your files.

Thanks ! I thought there were some more convoluted process but I couldn't picture out anything except extracting the whole archives and check up by hand.

Yes, I have a bunch of scripts that allow me to pick a Borg snapshot and then do stuff with it. One such action is `borg export-tar` that just creates a TAR file containing a full self-sufficient snapshot of your stuff.

Then just listing the files in the archive is a not-bad way to find an obvious problem. Or straight up unpacking it.

But if you're asking about a separate parity file that can be used to check and correct errors -- I haven't done that.
