Hi Erwan,
Could you include your configuration again?
" grep -v -e ^\# -v -e ^$ /etc/flexbackup.conf  "
will give us just your active configuration.

What output do you get from: " mt status " ?

Are you using version 1.2.1 of flexbackup?

OK - take compression and the tape out of your next test.
Make a directory /tmp/FlexTest,
set these options and run flexbackup again.

$compress = 'false';
$device = '/tmp/FlexTest/';

Now "  flexbackup -test-tape-drive " will say,
'No use trying tape drive tests on directories!',
but it will tell you if the rest of your syntax is correct.

If you get no errors, run it again without compression but with the tape:
$compress = 'false';
$device = '/dev/nst0';

Please answer the list rather than me personally,
so that others may benefit and offer further advice.

Good luck,
