We made it with a trick. We use a file auto changer, (virtual
autochanger). We then have two devices and several virtual tapes. Now it
is possible to backup and restore at the same time from a file-device.
Only one restriction is, that you can not use the same virtual tape for
backup and restore at the same time.

Maybe this will help you.
