+## Set Up Backups
+
+Your homelab includes comprehensive backup solutions. The default setup includes Backrest (Restic-based) for automated backups.
+
+### Quick Backup Setup
+
+1. **Access Backrest**: `https://backrest.yourdomain.duckdns.org`
+2. **Configure repositories**: Add local or cloud storage destinations
+3. **Set up schedules**: Configure automatic backup schedules
+4. **Add backup jobs**: Create jobs for your important data
+
+### What to Back Up
+
+- **Configuration files**: `/opt/stacks/*/config/` directories
+- **Databases**: Service-specific database volumes
+- **User data**: Nextcloud files, Git repositories, etc.
+- **Media libraries**: Movies, TV shows, music (if space allows)
+
+### Backup Commands
+
+```bash
+# Manual backup of a volume
+docker run --rm \
+  -v source-volume:/data \
+  -v /mnt/backups:/backup \
+  busybox tar czf /backup/volume-backup-$(date +%Y%m%d).tar.gz /data
