What is the type of data and are you using compression?  I wouldn't
expect that from an Oracle Database but if you are using compression
then I could see 2:1 numbers comparing backed up data to disk.  I've got
a "report" server with hundreds of thousands of HTML files that exists
on a 350GB Lun that is actually 1TB of data.

Subject: [Veritas-bu] Backing Up Too Much Information

I didn't think I'd ever say that but I am backing up too much data.  I
am running NBU 6.0 MP4, Windows Master/Media/Clients.  I have a client
with four 500GB volumes and my full backups from this weekend are
already at 1.7TB and still climbing.  I have seen this twice before and
it will end up backing up about twice as much data as is actually on the
client so I can only assume it's getting everything twice.  Does anyone
know how and why this happens and do you have any suggestions on how to
avoid it.

Thanks,
Randy
