Netbackup supplies a modified copy of tar with the netbackup client. You can 
even download the source code from the netbckup support web site. The source 
changes include the support for multiplexed tapes. 

I suspect that you still will not be able to read the tape with this version of 
tar as the being of the tar file would be missing. With a lot of work you might 
be able to use the tar source as a base to read the data and lay it down to 
disk.

Istvan,

You may not be able to use tar to recover data from the tape.  It
depends on how the tapes were written.  If they were multiplexed with
multiple streams of data going to them tar generally cannot read this.
 If they were written as a single stream you most likely can recover
data from the tape(s) using the mt command and options as David has
pointed out.

I've had instances where one tape failed to read or write in one drive
but worked in another.  If you have additional drives free you may try
disabling the drive it failed on last time and let it try to read from
another drive.
