After erasing,
i'll give you all infos about each questions you asked to
me.
What output do you get from: " mt status "?
[EMAIL PROTECTED] local]# mt -f /dev/st0
status
SCSI 2 tape drive:File number=0, block
number=0, partition=0.Tape block size 4096 bytes. Density code 0x47(
TR-5).Soft error count since last status=0General status bits on(
4101):BOT ONLINE IM_REP_EN
Are you using version 1.2.1 of flexbackup?
Yes
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.
Say nothing so
syntax ok
If you get no errors, run it again withoutc
ompression but with the tape:
$compress = 'false';
$device = '/dev/nst0';
[EMAIL PROTECTED] flextest]# flexbackup
-test-tape-drive -compress=false
-device=st0
flexbackup version 1.2.1 (http://flexbackup.sourceforge.net)/etc/flexbackup.conf
syntax OK

SO I've tried to see what is talking about this
/tmp/test.
I modified the script and I copy them into a
directory and when i
open it it was just the
/usr/bin/flexbackup.
SO no idea but I continue.
Thanks a lot for your help

Dear Erwan,

Dear Flexbackup users,
I've tried all blksize between 0 and 512
which my max, and none of
this values is correct, so anyone can
explain to me, where i'm wrong.
Here is my Flexbackup.conf
I assume you are using linux, and you should
first change this setting:
$device = '/dev/st0';
to
$device = '/dev/nst0';
This is very important!
Dell Powervault 100T DAT 72 with magnetic
tape of 36-72 GB.
If your tape drive has compression turned on,
you should not use
software compression.
I would recommend using software compression
where possible as you
will get better predictions on size, and you
will get better
portability of your backups.
It's far easier to recompile bzip2 for a new
platform than it is to
reverse engineer a compression algorithm on a
chip when your Dell tape drive dies.
What errors are you seeing in
/var/log/flexbackup ?
Why do you feel that the blks
