I just started getting into self hosting using docker compose and I wonder about possible backup solutions. I only have to safe my docker config so far, but I want host files as well. What software and hardware are you using for backup?
Someone on lemmy here suggested Restic, a backup solution written in Go.
I back up to an internal 4TB HDD every 30 minutes. My most important files are stored in an encrypted file storage online in the cloud.
Restic is good stuff.
