+## backups
+
+backups are done with [vykar](https://vykar.borgbase.com) to [borgbase](https://borgbase.com)
+
+always remember to `docker compose stop` before doing any of this!
+
+**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 6 * * * /home/admin/atom.town/scripts/volume-backup.sh
+  ```
+
+**restoring**
+
+the restore process is kind of fucked up but doable
+
+- restore on new system
+  - run `vykar list` to find a snapshot to use
+  - `sudo rm -rf /var/lib/docker/volumes/`
+  - then `sudo vykar restore abcd1234 /var/lib/docker/volumes/`
+  - figure out the UID:GID for all containers and `sudo chown -R UID:GID /var/lib/docker/volumes/.../_data/` their respective volumes
+- restore on same system
+  - run `vykar list` to find a snapshot to use
+  - then `sudo vykar restore abcd1234 /var/lib/docker/volumes/`
