Dear Shon I have a similar situation and solved it byusing this stargegy.
Firstly the disk volumes should be treated as "Tape" drives in that only onle volume can be opened at a time but you can have many concurrent jobs writing to that volume - my setting is for a maximum of 5 concurrent jobs/ I write data to a LaCie 1 TB disc using Firewire and get throughput of about 60 GB / hr. If you have several customers and can group them then one option is to partition your disc so that each group uses a different partition and this can be seen as a different "tape" drive and the jobs should write to each partition concurrently. As for full backups I use job migration - ie the jobs are written to disc and then migrated to tape. If you need my config files I will email them to you.
