I thought everybody here might be interested to know that our technical product managers has written and posted several excellent technical whitepapers. They happen to be listed under whitepapers on symantec.com/netbackup.
In particular, I'd recommend the following by Alex Davies - long time guru of NBU.
NetBackup 6.5 Disk Based Data ProtectionThis paper gives an overview of the disk based data protection technologies included with Veritas NetBackup 6.5 as well as recommendations on when to use the different disk based options.
And another great piece called good, better, best by another long time guru, Bill Roth.
I would not bug readers of the board if I didn't see great technical value in these papers. Let me know what you think.
