Hi Niall.
Yes, I've already tried all this feature.
 For the compression to I've already tried bzip, gzip, hardware and so on.
My impression is the next one.
After each 
flexbackup-test-tape-drive
It send me

Comparing...
directory /etc/flexbackup.conf and /tmp/test2.10734 are différents

FAILURE! Problem with tape driver or parameters.  Please see the FAQ
or try changing the $blksize, $pad_blocks, or $mt_blksize settings.

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

I assume you are using linux, and you should first change this setting:
> $device = '/dev/st0';
to
 $device = '/dev/nst0';
This is very important!

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 blksize is your problem?

Niall
