I'd recommend something like 2 to 8 GB, but this is not based on any 
testing at all.

I'm having clients with disk-based setups and that size range worked ok, 
but it also depends on your jobs. If you expect to restore mainly full 
jobs, setting your volumes up so that they contain only one job is one 
possibility, but usually I prefer to have a large number of smaller volumes.

Also, using volumes sizes of about 4.5 GB is nice when you want to 
export volumes to DVD.

By the way: Keep in mind that changing the configuration only affects 
newly created volumes, not existing ones. The 'update' command is needed 
to modify existing volume entries in the catalog.

Existing volumes will only be truncated when they are recycled.

VolFiles is the number of logical files in a volume. This is tape 
terminology - with tapes, you (usually) position to a certain file and 
read sequentially from then on.

File marks take up tape space, so you've got to find a good balance 
obetween smaller file sizes and a larger number of files for fast 
positioning, and larger files with more usable tape capacity.

You don't have to worry about this with disk based volumes - these have 
other peculiarities. As you found out.
