Gerry,
I'll have to forward this off to the network admin in order to get
those answers for you.

What are the particulars on the server? Also, are you backing up to a
database, or is this solely the rasters? (Sorry, I'm looking at it
now,
but I've not had time to grok it all)... I'm thinking "Server" at this
point, as you're moving a lot of bits and thus have a lot of diskIO.
If you're talking 'bout a SCSI-based RAID5, you've got some of the
overhead covered. If you're using a slow IDE disk, it's a lot worse.
