oui et non.
Il y a tellement longtemps que je n'ai pas bidouillé avec linux que j'ai
beaucoup de mal à me souvenir...
La commande que j'ai faite a duré de 21h à 5h du matin et c'est terminé par

Je pense qu'il va falloir que je recommence avec la commande d'olivier.
dd if=/dev/sda bs=4096| gzip -9 > /media/sauv-dd/dd-am/dd-20150901.img.gz
mais que faire pour ne plus avoir d'erreur?
Cela me parait très long pour sauvegarder un disque. C'est normal ou pas?
Anne
