+backups are done with [vykar](https://vykar.borgbase.com) to [borgbase](https://borgbase.com)
+
+**creating**
 - if on a new borgbase repo, run `vykar init` first
+- to back up, run `sudo vykar backup` (sudo required as we are accessing `/var/lib/docker/volumes/`)
 - to back up automatically, run `sudo EDITOR=micro crontab -e` and add the following:
   ```
   TZ=UTC
   0 * * * * /home/admin/thingy/scripts/volume-backup.sh
   ```
 
+**restoring**
+- to restore the backup, run `vykar list` to find a snapshot to use, then `sudo vykar restore abcd1234 /var/lib/docker/volumes/`
+
 ## todo
 - further secure the server (ratelimiting, hardening...)
 - more services
