It is good practice to take backup media off-site in case of a disaster. In the shell script example the backup media is another server providing an NFS share. In all likelihood taking the NFS server to another location would not be practical. Depending upon connection speeds it may be an option to copy the archive file over a WAN link to a server in another location.
Il est conseillé de prendre des supports de sauvegarde hors site en cas de catastrophe. Dans l'exemple de ce script shell le support de sauvegarde est un autre serveur fournissant un partage NFS. Selon toute vraisemblance, prendre le serveur NFS vers un autre emplacement ne serait pas pratique. Selon les vitesses de connexion, une option possible est de copier le fichier d'archive via une liaison WAN à un serveur à un autre endroit.

Another option is to copy the archive file to an external hard drive which can then be taken off-site. Since the price of external hard drives continue to decrease, it may be cost-effective to use two drives for each archive level. This would allow you to have one external drive attached to the backup server and one in another location.
Une autre option est de copier le fichier d'archive vers[nbsp]un disque dur externe qui peut ensuite être retiré du site. Comme le prix des disques durs externes continue de diminuer, il peut être rentable d'utiliser deux lecteurs pour chaque niveau d'archive. Cela vous permettra d'avoir un disque dur externe connecté au serveur de sauvegarde et un dans un autre emplacement.

A tape drive attached to the server can be used instead of an NFS share. Using a tape drive simplifies archive rotation, and makes taking the media off-site easier as well.
Un lecteur de bande connecté au serveur peut être utilisé au lieu d'un partage NFS. L'utilisation d'un lecteur de bande simplifie la rotation des archives, et permet également de prendre les médias hors du site plus facilement.

When using a tape drive, the filename portions of the script aren't needed because the data is sent directly to the tape device. Some commands to manipulate the tape are needed. This is accomplished using <application>mt</application>, a magnetic tape control utility part of the <application>cpio</application> package.
Lors de l'utilisation d'un lecteur de bandes, les parties de nom de fichier du script ne sont pas nécessaires parce que les données sont envoyées directement au périphérique à bande. Certaines commandes de manipulation de la bande sont nécessaires. Ceci est accompli en utilisant <application>mt</application>, un utilitaire de contrôle de bandes magnétiques faisant parti du paquet <application>cpio</application>.

The default device name for a SCSI tape drive is <filename>/dev/st0</filename>. Use the appropriate device path for your system.
Le nom de périphérique par défaut pour un lecteur de bandes SCSI est <filename>/dev/st0</filename>. Employez le chemin correspondant à votre système.
