You cannot use the same tape as a NBU catalog backup because the tape is
mark in its header as a standard tar tape. NetBackup, although uses gnutar,
writes a special header for NBU backups. These two kind of backups cannot
exist on the same tape.

Subject: [Veritas-bu] Questions about bpduplicate


There's something about bpduplicate that I don't get...

1.  I backed up my NetBackup catalog manually as follows:
1.1  tpreq -rv 000033 -p [pool] -f /tmp/blah
1.2  bpbackupdb -v -tpath /tmp/blah

Next, I wanted to duplicate last night's CINC backup to the same media ID.
I tried:

1.3  bpduplicate -dstunit [my_robot] -L [logfile] -backupid [id] -id 000033

Here, bpduplicate complained that it "found no images or media matching the
selection criteria."  So I unmounted the tape (tpunmount /tmp/blah).

2.  Again I tried:
2.1  bpduplicate -dstunit [my_robot] -L [logfile] -backupid [id] -id 000033

And kept getting the same error.  I tried specifying the volume pool as well
as the media id, and that didn't work either.  Finally I just specified only
the pool, and not the media id, and the command ran.  Of course it selected
a different tape from the same pool.

How come I couldn't use the same tape to which I had just backed up the
catalog?  What did I do wrong?

(I am running NetBackup BusinesServer 3.4GA on HP-UX 11.00)

Thanks very much.
