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.
