A duplicate is just another backup with a different copy number in the image
catalog.
Duplicates and backups can coexist on the same tape (in fact, NBU may even try
to dup a tape to itself... which is why you should duplicate to a different
pool than where the original is).
Catalog information does not get put on the tape (when you send tapes
off-site, you should make sure the catalog information is sent off-site
somehow as well). An import will read everything off of the tape to create
the catalog (that's why it takes a very long time).
To make this a one-time thing you could either use a different retention that
none of your backups are using (asuming you have the default and don't allow
multiple retentions on the same media) or create a temporary pool, put a tape
in it and specify that pool for the backup. Check the catalog to make sure
before you send it away, but this should put it on a separate tape.

[Veritas-bu] Sending NB tapes to customers

I need to backup some data to send to one of our customers, however I'm unsure
how safe/easy this is.
I _believe_ that I should simply do a backup, then duplicate it and send them
the tape. Theoretically they should be able to put it in a drive connected to
their NetBackup server and import the tape. Right?
I'm not sure if this is a good way to go. I'd much rather just tar the data
to tape so I _know_ they can get the data from tape, but they are asking for a
NB tape.
Followup question is, the backup I'm doing for them is being done in a brand
new class for a one-time backup (since we only want to give them a small
amount of data, not a full regular backup). Is there a way I could make this
one-time backup ready for export without having to make it and then duplicate
it? I believe the reason I have to do the duplicate on this tape is because
normal backups don't put the catalog info on the same tape as the backup,
untill you do a duplicate, right?
.........or do I need NB Vault for this sorta thing?
