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.
