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 use the “||” operator in bash scripts to send a curl command to ntfy if the backup fails. But the healthchecks option is a little bit more robust since you wouldn’t get a notification if your system crashed and ntfy dies too. I believe you can also do this with Uptime Kuma if you want to go self-hosted on a remote server.
