What I do is this:

I have 14 tape drives in two datacenters, shared by 9 media servers. I 
have created a storage unit for each media server, all but one have been 
allocated one drive to use. The one exception has been allocated two 
drives. In total, I have only allocated 10 of 14 drives to be used for 
backups. This ensures that I have 4 drives available for restores. 
Primarily, this is for DR, in the event of disaster, I have the capacity 
to perform an acceptable number of simultaneous restores, without 
impacting the system's capability to continue taking backups.

HTH,

Steve
