[Veritas-bu] In-File Delta Technology

[Jorge Fábregas]

Hello everyone,

I'm still learning Netbackup (got around 1.5 years working with it) and I'm 
wondering... Is there a way to perform incremental backups using in-file 
delta technology (backup only changes within a file)?  I've seen a lot of 
features/options for Netbackup but I have never seen this...If indeed there 
isn't ...why isn't this type of ESSENTIAL technology part of Netbackup?

Just as an aside, I recently started backing up a server that runs "MS Virtual 
Server" that has around 9 guests...I back them up at night (obviously after 
shutting down the guests) and I know 5 of those 9 guests seldomly change but 
as you can imagine...because the timestamp on the virtual-hard-disks 
change ...they're backed up COMPLETELY.  The end result: I'm almost 
performing a FULL backup every day even though it's an incremental 
schedule   :(  

I'll appreciate your feedback. 

Thanks!

All the best,
Jorge
