Because we had already the option to backup files directly to tape, it was already possible to backup file shares to tape without backing it up to disk before. But this was limited at least to performance. This will be be much better in v12.
Another limitation was that it was not possible to copy a NAS backup to tape. This will be available in v12.
At least in v12 beta media pools are limited to Standard media Pools and WORM Media Pools.
