Thanks everyone for all the useful information. I think my proposal will be:

Install master (or media server) offsite in secondary building. This server 
will be connected to a disk array filled with cheap disks in RAID 5.

I will perform incremental backups to disk Mon - Thurs and a Full backup on 
Friday (still to disk). During Saturday day, I will write the disks to tape and 
send to DR unit on Monday morning. The worst case scenario is that I loose the 
data onsite, the filer and will have to restore from tape that could be one 
week out of date - Management agree this is an acceptable loss. Does this sound 
sensible to everyone?

Thanks,
Timothy.

Well actually you can (at least in 3.4.1 I've seen around, but I think it
should be there in 3.4 also).
You can create a Storage Unit of type "Disk" and subsequently specify the
Media Server and the absolute path to a directory (of the Media server).
Then in the class definition you select as "Class storage unit" the name of
the newly created storage unit.
If you would like to have your disk backups to the other building you'll
need to set up a media server there.
