How do you setup your environment to get 2 physical tapes? do you backup
to 2 tapes at the same time or do you use vault to to dup your tapes?

I would add that, yes, it would be a good idea to keep images on the VTL
for possible restores.  However, if you need the space, then you should
remove those images from the VTL as soon as they have been successfully
duped.  Our practice is to make two physical tape copies, one for
on-site and the other for off-site for DR purposes.  That way we have a
physical tape on-site with the backup image for quick restore so that we
don't have to do any recalls from offsite.

I would change the retention in your netbackup policies to be inline
with how long you want the data kept on the VTL.
When you duplicate/vault you can specify how long you want the data kept
on the "tape" copy, independantly......then the VTL copy will expire
itself after the amount of time you've specified in the original policy.
 
you don't really want to expire the VTL copy as soon as it's duplicated
to tape.....in theory, the best practice would be to dupe it to tape as
soon as possible, but keep it on the disk/VTL as long as you can (as
long as you have sufficient space to do "tonight's" backup) that way
your restores come from disk as much as posisble.

        Nb 5.0 mp6 Solaris 9 EMC CDL VTL 

        Ok here is the situation. We are testing this Emc CDL VTL. We
backup data to the VTL and now need to get the data on the VTL copied to
physical tape and then expire the image on the VTL. We were trying to
use vault to perform the copy but unfortunately it will not expire the
images on the VTL because it thinks the VTL are tapes. I understand that
it will work if it was a DSU and we were copying the data to tape but
since in the eyes of netbackup this is a tape to tape copy it is not
designed to expire tape copies. This I just confirmed with Symantec. SO
I think I need a script that will run copy and expire commands. Is
anyone else using the EMC CDL VTL and has run into this same problem?
Does any have a script that will perform this function?
