Two caveats:
1. You can't do this if you've multiplexed the tape, or if you have =
chosen a
fragment size of anything other than 0.
2. You can't do this on Windows unless you have the MKS toolkit
(http://www.mkssoftware.com/products/tk/ds_tksa.asp)
    (That's the only way _I_ know of to get the MT command on Windows, =
and
you have to download the ASPI drivers for your SCSI card.)

Hi,
=20
You can do it but you need to position yourself on the right record on =
the
tape because one out of two record is a NetBackup header. You will also =
have
some troubles resolving links if you are not restoring on the original
location.

.

Hope this helps

Hi,=20

Is there a "quick" way of extracting/recoverying the content of a =
NetBackup
tape withou having to identify the directoryies/files that make up =
images on
the Tape.

I have tracked the data and know what tape it is on but I seem to have =
to
identify it all to recovery it through the gui.

Because Netbackup is using 'gnutar', can I use a gnutar cmd to extract =
'all'
of the backup images on the tape.=20

Thanks.=20
