[flexbackup-help] Pb recover from /dev/st0 - tar+gzip

[Philippe A. <phi...@ci...>]

Hello

I have a crash disk, I LOST ALL MY DATA

and I try to recover it, bur I have some probl=E8mes, maybe you could hel=
p=20
me please !

I want only recover /var/spool/mail !

I'm in /tmp to recover ...
When I try
tar xzf /dev/st0 /var/spool/mail/
it said to me doesn't find in archive (french translation)

When I try
mt -f /dev/st0 rewind
mt -f /dev/st0 fsf 0
flexbackup --extract
It's extract only the backuped /etc ! Why ?

If I want only recover the file 14 (/var/spool/mail see list under), can=20
I do :

mt -f /dev/st0 rewind
mt -f /dev/st0 fsf 14
flexbackup --extract

Is it correct ?

How do I only recover my var/spool/mail ...

Thanks a lot in advance for your Help

Philippe
