I would like to share an add-on I created to back-up my HassOS install. The built-in snapshots system was unable to back-up my 5GiB+ influxdb, so I decided to build something using restic.
It does take some work to set it up, but I hope it helps someone.
You can find the add-on on Github.
That was exactly my concern
No, I haven’t used it, yet. It seems you would need to update the addon-image first, because there’s an issue regarding the common S6-overlay error.
I’d love to find a working a solution like this very soon, though. At some point I decided that I don’t want to maintain a second server in my home, so Home Assistant must cope for everything, including my 500GB of photos. I don’t want to do a full (generational) backup on them every night like I do on all the other stuff
