 ## Logs
 
-Nginx Proxy Manager writes access/error logs under `/data/logs`, which is mounted outside of `VOL_PATH`. Since logs shouldn't be backed up with the rest of the data, they're mounted separately via `LOG_PATH`, which defaults to `/var/log/containers/nginx-proxy-manager/`. If you'd rather back up/sync logs with the rest of the data, just remove the logs volume.

+## Upgrade (and backup)
+
+Back up the data volume with restic before upgrading, so you can restore it if the new version doesn't come up cleanly. Logs aren't included since they're not needed for a restore.
+
+```bash
+restic backup /data/nginx-proxy-manager
+```
+
+Once the backup completes, pull the new image and recreate the container:
+
+```bash
+docker compose pull
+docker compose up -d
+```
+
+Or, if you're running the `docker run` version instead of compose:
+
+```bash
+docker pull jc21/nginx-proxy-manager:latest
+docker stop nginx-proxy-manager
+docker rm nginx-proxy-manager
+docker run -d \
+  --name nginx-proxy-manager \
+  --restart unless-stopped \

+  -v "/var/log/containers/nginx-proxy-manager:/data/logs" \
+  jc21/nginx-proxy-manager:latest
+```
+
+If something goes wrong, restore the snapshot with `restic restore latest --target /` (or `restic snapshots` to pick an earlier one) and start the old container again.
