| 3 | Normally, if you want to back up a data volume, you run a new container using the volume you want to back up, then execute the tar command to produce an archive of the volume content: |
||
| 4 | |||
| 5 | ``` |
||
| 6 | docker run --rm \ |
||
| 7 | -v "$VOLUME_NAME":/backup-volume \ |
||
| 8 | -v "$(pwd)":/backup \ |
||
| 9 | busybox \ |
||
| 10 | tar -zcvf /backup/my-backup.tar.gz /backup-volume |
||
| 11 | ``` |
||
| 12 | |||
| 13 | To restore a volume with an existing backup, you can run a new container that mounts the target volume and executes the tar command to decompress the archive into the target volume. |
