Hi,
I found a solution :
Copy  /usr/share/backuppc/bin/BackupPC_archiveHost to BackupPC_archiveHost2
Edit the file and change this :
# $cmd .= ">> $outLoc";                              <= Comment this line
$cmd .= "| dd of=$outLoc obs=10k";           <= And add this one

With this new line you replace cat with dd and you can set the block size.

Then edit this 5 lines of the config.pl of your archive host :
$Conf{ArchiveDest} = '/dev/nst0';

$Conf{ArchiveComp} = 'none';

$Conf{ArchivePar} = 0;

$Conf{ArchiveSplit} = 0;

$Conf{ArchiveClientCmd} = '$Installdir/bin/BackupPC_archiveHost2'

Rewind your tape with : mt -f /dev/nst0 rewind
Go to Backuppc interface and archive a host to the tape
Wait for the end of archive
Rewind the tape : mt -f /dev/nst0 rewind
And print file list of the tape with : tar -tvf /dev/nst0
Or extract the files with : tar xvf /dev/nst0

If you have multiples hosts on the tape, you con set the tape to the 
good position before extracting the files :
mt -f /dev/nst0 fsf 1
Set the tape to the next archive

mt -f /dev/nst0 bsf 1
Set the tape to the previous archive

The next step is to use cron, I'm working on it !
Bye
