Docker: Limitations

Granular restore (Single Item Restore) is not supported. This feature could be implemented in the future.
Only Full level backups are possible. This is a Docker limitation for containers and images. For volume backup this limitation could be removed in the future.
You can restore volume files data into the same volume name only. This limitation could be removed in the future.
You will always overwrite restored volume files data regardless of Replace parameter value. This limitation will be removed in the future.
Backup or restore of the Volume data files for remote Docker service is unsupported. In this case you should get a following warning when want to explicitly backup a such data:
```
Warning: dkcommctx: Docker Volume backup with docker_host is unsupported!
```
and a following warning when want to restore:
```
Warning: docker: Docker Volume restore with docker_host is unsupported! \
All volumes restore skipped.
```
If you access the remote Docker service outside plugin configuration then your job might hung. This limitation will be removed in the future.
The restart command has limitations with plugins, as it initiates the Job from scratch rather than continuing it. Bacula determines whether a Job is restarted or continued, but using the restart command will result in a new Job.
