We have a document mgt application that stores gobs of files (documents) 
that are tracked by a bunch of databases.  We were hitting the same kind 
of problems you are having in getting it backed up.  And, even thought we 
had some kind of backup, it was clear that the server could never be 
restored in a DR situation.  One of the first things we did to help was to 
SRDF the system (EMC storage) to the DR site.  Over time it became clear 
that the overall backup/recovery design for this system was collapsing 
under it's own weight.  We eventually had to completely change ithe way 
backup/recovery worked - we went to system of all snapshots and 
replication.  Part of this was changing it's storage to NetApp, but EMC 
has similar tools.

Good idea.   No Netapp, it's on EMC DMX.  But I'll check and see if they 
can snap that....

Maybe a complete step change is needed here.

It's worth thinking about a netapp/N series and snapvaulting off to a 2nd 
one. That works even with a huge environment.

biggest problem isnt now, it's when u need to restore those 70 million 
files. So reducing the amount of files either by HSM or archiving isnt 
even an option, it's something you need todo. Doing RAID, box mirroring 
and such wont protect the system from logical errors, so counting on HW 
todo the job just wont do it. The restore times needs to be acceptable 
from TSM.

browsing the fileserver, backing it up, and in the end, restoring it.
