Depending on your setup and the application(s) you are running, this might involve other steps to be taken still.
---
If you want to rollback an entire volume to an earlier backup snapshot (recommended for database volumes):
- Trigger a manual backup if necessary (see `Manually triggering a backup`).
- Stop the container(s) that are using the volume.
- If volume was initially created using docker-compose, find out exact volume name using:
```console
docker volume ls
```
- Remove existing volume (the example assumes it's named `data`):
```console
docker volume rm data
```
- Create new volume with the same name and restore a snapshot:
```console
docker run --rm -it -v data:/backup/my-app-backup -v /path/to/local_backups:/archive:ro alpine tar -xvzf /archive/full_backup_filename.tar.gz
```
- Restart the container(s) that are using the volume.
### Set the timezone the container runs in
By default a container based on this image will run in the UTC timezone.
