Pb recover from /dev/st0 - flexbackup - tar+gzip
Bonjour
J'ai subit un crash disk et j'ai TOUT perdu ! :-(
Mais heureusement j'ai configuré un flexbackup qui me bakupais tout les
jours sur 7 jours mes données ...
Mais j'essaie de les recuperer et j'ai besoin d'aide, car j'ai quelques
soucis !
A la limite, le plus important est /var/spool/mail !
Je me place dans /tmp ...
Lorsque que j'essaie
tar xzf /dev/st0 /var/spool/mail/
il me dit :
tar: Escamotage jusqu'à la prochaine en-tête.
tar: Escamotage jusqu'à la prochaine en-tête.
tar: /var/spool/mail: ne peut être retrouvé dans l'archive.
tar: Statut d'erreur reporté d'erreurs précédentes.
Lorsque que j'essaie
mt -f /dev/st0 rewind
mt -f /dev/st0 fsf 0
flexbackup --extract
Il m'extrait seulement le repertoire backupé /etc ! Pourquoi ?
Si je voudrais récuperer le fichier 14 (/var/spool/mail voir liste plus
bas), devrais-je faire :
mt -f /dev/st0 rewind
mt -f /dev/st0 fsf 14
flexbackup --extract
Est-ce bien la commande ?
Je voudrais simplement /var/spool/mail ...
Merci d'avance pour votre aide
Philippe
