The skipping past the headers thing works but only if you're doing
non-multiplexed backups. Mux'd backups can't be done this way. There's the
whole "where is the file" thing that has to be considered there, too.
Considering the ease of the bpsyncinfo method, why not do it that way?
For offsites, I cut special catalog backups.
Select a scratch tape
tpreq to mount the tape
bpbackupdb to backup the catalogs to the tape
tpunmount to umount the tape
change the volume group, return dates, etc. & eject

Subject: RE: [Veritas-bu] Catalog backup question
Here was my original thinking on this. Because our catalog backup to tape
was taking too long we went to disk. The disk backup is also copied to
another offsite datacenter via srdf. This only gives me a backup catalog
for 24 hours and I don't feel real comfortable with that. Numerous posts
state that a NetBackup tape can be restored via tar after bypassing the
headers. Isn't it possible to copy the tape via tar back down to my catalog
disk backup area then restore the catalog from there? My personal opinion
is that NetBackup doesn't make backing up and keeping offsite copies of
their catalog very easy or timely. Bottom line is I'm just trying to add a
little more insurance to the catalog backups but don't want to waste the
resources if this isn't necessary.
Opinions or ideas how others are doing this are appreciated. Thanks in
advance.

If you backup your catalog via an NB policy then you'll have to install NB &
the catalog in order to restore the catalog. Very circular. The bysyncinfo
method uses a simple tar to tape so that Netbackup is not required to be
installed in order to read the tape.
So, in short, "yes" you can back it up but "no" it's not usable to restore
Netbackup.

Subject: [Veritas-bu] Catalog backup question
Our environment is:
Netbackup Enterprise 5.1
Master Server on HP-UX 11i
Media Server on HP-UX 11i
SureStore 20/700 Library (LTO-1)
We are currently backing up our catalog to disk. If I also back this
catalog disk image to tape via a normal NetBackup policy can I use this for
my offsite catalog backup? Or do I have to run "bpsynacinfo -doBackup" and
point it to tape to have a valid catalog backup on tape?
