Re: recover data from tape

Hello,


   I'd like to see what are there as data on a tape but not in using
amanda commands. I tried with tar and dd command without result. Does
someone know how I could do that ?


From the docs/RESTORE file:

#!/bin/sh
TAPEDEV=</dev/nrtape>
while mt -f $TAPEDEV fsf 1 ; do
  dd if=$TAPEDEV bs=32k count=1 | head -1
  sleep 1
done

Is this what you're looking for?
tapedev must be the no-rewind device.
head -1 gives the contents;  head -3 gives the command to restore too.

Or do you want the index of contents of one particular file on tape,
then:
  mt -f $TAPEDEV rewind
  mt -f $TAPEDEV fsf <somenumber>
and read the file, skipping over the first 32k amanda header,
with a suitable command (gnutar or restore, with gzip in between
if needed) e.g. for a compressed gnutar image:
  dd if=$TAPEDEV bs=32k skip=1 | gzip -d | gtar -tvf -
