+* we use restic to produce small & encrypted backups
+* backup is scheduled at `schedule: "10 23 * * *"`
+* Gitea stores files in `/data/gitea` and `/data/git/repositories`, these files are backed up. 
+* The postgres db is also backed up
+
+## Manual init the restic repository for the first time
+
+1. apply backup-and-restore pod:   
+   `kubectl scale deployment backup-restore --replicas=1`
+2. exec into pod and execute restore pod (press tab to get your exact pod name)   
+   `kubectl exec -it backup-restore-... -- /usr/local/bin/init.sh`
+3. remove backup-and-restore pod:   
+   `kubectl scale deployment backup-restore --replicas=0`
