Hello Jim
My understanding is that to start recording the index info required for DAR in
the netbackup catalog you need to upgrade to NBU 4.5 or higher. The code to
use this newly recorded index data for restores is included in NBU 4.5FP3.
I was able to restore a small file in less then 5 minutes, and this included
the time to mount a dlt tape cart.
There are some limitations in how many files can be entered for restore at one
time without falling back to the old method of doing restores.

Hello.
A file that would fit on a floppy disk can take over 12 hours to
restore in
my environment.
Pretty bad for customer service.
My environment is an instance of NBU 3.2 capturing a weekly backup of a
Network Appliance Filer using an NDMP scheme to a locally attached DLT
library. The Filer can be capturing several
terabytes of data. A restore can call for the loading of umpteen DLT
IV
tapes for this
one itty-bitty-file.
My recent postings to the Veritas.Com newsgroup later proved that the
DAR
functionality required to get this one itty-bitty-file back in a more
reasonable time frame was not available in the NBU 3.x realm. My file
has
the latest ONTAPP OS.
I'm trying to ascertain and confirm that if I move from 3.x to 4.5 FP3,
the
environment will
allow me to take advantage of DAR and get my itty-bitty-file back a bit
sooner.
Please let me know your thoughts.
Sincerely
Jim
