How do you run more than "a single backup process" against the filespaces
with very many files?

We have several nt servers with large (30+gig) raid
arrays.  Backup takes quite a awhile to run but restores are even more
It can take up to an half hour for a restore to display files requested for

Is there any way to improve performance for these restores?

btw, we are running v2 server on aix.
