test the contenent of backup tape

[ouazir]

i work on hpux v3, i try to view the contenent of my tape after i have backing up my data with
fbackup -v -f /dev/rmt/0mb -i /backapp/..
this instruction
frecover -f /dev/rmt/0mb -x -N -v
gives me this result
erp1 /entpscript#frecover -f /dev/rmt/0mb -x -N -v
frecover(5409): unable to read volume header
frecover(5418): not an fbackup volume; unable to read volume header
frecover(2105): did not find expected file marker
frecover(5412): Do you wish to try to salvage this volume? (^[yY]/^[nN]
frecover(5413): attempting to read backup following bad volume header
frecover(5426): read error while attempting to read index. Skipping.
what's the problem?

Hello Ouazir. HAve you tried a read/write using L&TT . Probably the tape was not formatted before the test backup. Could be an issue with the tar file that you have created.

[ouazir]

what do you mean by read/write using L&TT
i think that this a library tape tools that i already used it for checking device status for example?
mt -f /dev/rmt/0mb status
file:0
block:0
that is mean that no data to be restored.
i want to indicate that i tryed to backup a compressed file such as
file.tar.gz with
fbackup -f /dev/rmt/0mb -i /backapp/backapp.tar.gz
is it correct?
