Thanks, it works now.
But I have an other problem. I have a shared folder (NFS) on a NAS. Backup is ok but when I try to restore, the connexion is refused.
The message is :
"mount.nfs : rpc.statd is not running but it is required for remote locking.
mount.nfs : Either use '-o nolock' to keep locks local, or start statd."
Do you have any idea for this ?
Thanks's for your help,
