The size of the database mostly depend on the number of  
files/directories and your retention policy.

You should set it by drive and calculate for the number of parallel  
jobs you are using.

If you backup all 8 machines concurrently you should set your Job  
Spool Size to something around "available diskspace / 8". Also be  
aware that you need additional spool space for spooling attributes  
which is enabled by default when using data spooling. Think of data  
spooling as some form of cache to pack things together before  
committing to database and tape.
