Hi selfhosting community! At the moment I have my services set up with nix. They store their data on a btrfs subvolume which I can easily snapshot.
For backup I configured btrbk to send the snapshots to a target pc. However I feel uneasy not knowing if the backups succeeded or not. Right now I would need to check manually on the target machine every so often.
How are you guys handling this problem? Custom scripts for btrfs send/receive? Is there a function in btrbk I overlooked where I can verify the state and get notified of problems?
I was looking into ntfy-sh, which looks optimal, but how can I know if the send/receive was successful?
I’m not familiar with btrbk specifically, but my backups all send a ping to https://healthchecks.io/ when they start and when they finish. healthchecks.io works by getting a simple curl request, similar to ntfy, but if that request doesn’t happen after a certain amount of time (or if you do a start request and a succeed/fail request and the job is taking too long) then it will notify you. It can use ntfy for notifications, but it can also send emails or use any of a number other services.
