rsync copies changed files. After that, the container is started (resumed)
again. This results in minimal downtime, but needs additional space
to hold the container copy.

When the container is on a local filesystem and the target storage of the backup
is an NFS server, you should set `--tmpdir` to reside on a local filesystem too,
as this will result in a many fold performance improvement.
Use of a local `tmpdir` is also required if you want to backup in `suspend`
mode a local container using ACLs to an NFS server.

`snapshot` mode::
For containers, this mode uses the snapshotting facilities of the
underlying storage. A snapshot will be made of the container volume,
and the snapshot content will be archived in a tar file.

For QemuServer, this mode will do a live backup similar to the
`suspend` mode, but without suspending/resuming the VM.
