Honestly, if you have that large of a backup set and the individual
files can be in the terabyte range, you might want to reconsider whether
spooling is the correct approach.  Remember, the primary purposes of
spooling are to allow a fast dump to disk of small backup sets followed
by a slower write out to tape (in order to free up clients as fast as
possible), or to prevent shoeshining when clients and/or the network
cannot transfer data fast enough to keep a high-speed tape drive streaming.
