 To checkout what's going on in the mount container type in the following command:

 ```bash
 docker run -it --entrypoint /bin/sh --rm --volumes-from {{container_name}} -v /Backups/:/Backups/ kevinveenbirkenbach/alpine-rsync
 ```
+## Manual Backup
+rsync -aPvv  '***{{source_path}}***/' ***{{destination_path}}***";

-## Setup
-Install pandas
+## Test
+Delete the volume.
+
+```bash
+docker rm -f container-name
+docker volume rm volume-name
+```
+
+Recover the volume:
+
+```bash
+docker volume create volume-name
+docker run --rm -v volume-name:/recover/ -v ~/backup/:/backup/ "kevinveenbirkenbach/alpine-rsync" sh -c "rsync -avv /backup/ /recover/"

+Restart the container.
