TIR backups are part of the base package.  A lot of us don't use it because
it increases load on the client & database size.  Basically it tracks
deletions & other OS functions (inode changes that don't alter mtime value)
and will avoid restoring files that were deleted during the restore window
(avoids restoring too much).

Overwrite on restore is simply a yes/no flag.  If a file exists during a
restore, regardless of timestamp, it will either be skipped or clobbered
depending on the Overwrite selection.  There is no "restore if newer only"
option.

Hi Tim,

Thanks for your quick reply. I will try on your answer 1. TIR - I am not
aware on this. Is this part of NBU 3.4 or some option?.

Regards,

Mani

1) You can run the report for the client in question and see how big the
backup was (under X it is xbpadm, reports, client backups)

2) if you are using true image recovery (and TIR backups) then no, otherwise
yes

3) on restore yes you can select overwrite (I'm not sure if it uses
date/timestamp)

Subject: [Veritas-bu] Many questions on netbackup (3.4)


Hi all,

I started working on netbackup (3.4 datacenter) for about 2 months now. I
worked on similar products (omniback, arcserve/alexandra). I have few
questions on how we achieve (or possible) in netbackup.

1) On restore how do we know the size of restore before submitting (I guess
no preview on 3.4)?.
2) If we are trying to restore a full backup and subsequent incrementals,
should we need to submit multiple restore for each date or single job can
restore all dates?. 
3) Is there any setting on netbackup to automatically overwrite on new
datestamp or size?.

One more last question:
I have a exchange backup which is backing 4 information store each as a new
stream. Sometime if one fails, my resubmission again kicks of all 4. I need
to kill other jobs. Is there any command line option in bpbackup to submit
for one stream only?.

Thanks for your help,

Mani Vasagan
