This is a good idea, I like it.
While not applicable to this request,
I would also document all of the images being expired so that in case you
do mess up, you have the bpimagelist output that you can use to go back
and unexpire, import, or have on hand to know which tapes need to be held
out of the library, etc.
My last bit of advise would be for when
you are scripting this, be sure to test the script with a couple of images
first to ensure it does exactly what you expect. CYA, CYA, CYA.

image question |

I may be overly cautious, but I would set copy 1's expiry
date to "tomorrow" rather than "now", so that I have
time to fix things if I somehow mess with the copy that I want to keep,
rather than having everything vanish instantly as would happen if I used
-d 0.
bpexpdate -backupid <backupid> -copy 1 -d 01/09/2010
Then a bpimagelist to make sure the expiration date on
each copy is they way I want it.

Typically we wouldn’t promote
the duplicate (copy 2) to primary first. We’d simply set its retention:
bpexpdate -backupid <backupID>
-d infinity -copy 2
Then for the original (copy
1) we’d set it to expire immediately:
bpexpdate -backupid <backupID>
-d 0 -copy 1
We wouldn’t specify media at
all as what we’re interested in is the images (which is what the backupid
refers to) not the media. Once all images on a given media are expired
then the media itself expires automatically.

Subject: [Veritas-bu] Duplication / expiring image question
Our environment, NBU 6.5.4 running on HP-UX
11-31 with a Data Domain VTL and MSL6060 tape library.
Our tape library wasn’t connected when we
ran our yearly backups and now that it is, I’m in the process of duplicating
the yearly backups from the VTL to tape to be moved offsite. I am
going through my process to insure I don’t miss any data
in the move and
only remove the original
of the duplicated
data. I have duplicated what was backed from one policy and set the
copy as primary. In the example below, the original was backed up
to D11233 and then
duplicated to 000789.
#
# bpimagelist -d 01/02/2010 -sl

#
What I now need to do is expire the D11233
VTL tape and leave
the 000789 one alone. After I RTFM I think the command below should
do what I want but would like some verification before pulling the trigger:
# bpexpdate –backupid
yos_sam1_1262415605
-m D11233 -d 0
Can anyone see a problem with the above, will
it only remove the images
on D11233 for the backup id of yos_sam1_1262415605 and leave anything else
alone? Is there better
way to do this?
Thanks in advance….
