Wow...That's better:

[EMAIL PROTECTED] cron.d]# time dd if=/dev/zero of=/dev/nst0 bs=2048k count=1024
1024+0 records in
1024+0 records out

real    0m27.593s
user    0m0.000s
sys     0m0.660s

Re: tar's default block size & shoe-shinning

Thank you for your answers Joshua, I will try a "dd" with bs=2048k. Then probably I will compile amanda...

Bouh I don't like to do that in a production environment....
