Can you write a bit more about their backup2disk setup? They must have
many very large raid arrays witch they then use as bacula sd-devices.

No doubt.

Accurate Backup together with Dedup would be a great feature (Bacula
already used the database for Accurate Backup, so adding a dedup
feature seems not too far away).

I'm happy with the performance of bacula and our LTO4 drives. A single
job is able to write with 130 MB/s to tape ;)
