+## Backups
+
+The service is running on retastokado, a 6TB ZFS mirrored pair at Scott's home.
+It has limited upload speed. Sanoid is configured, via NixOS config, to keep 48
+hourly, 14 daily, 3 monthly, and 1 yearly snapshot of the config (`/etc/ocis`)
+and data (`/var/lib/ocis`) volumes. Adding another zpool at another location and
+configuring Syncoid would provide a sound backup strategy.
