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.

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.

The default device name for a SCSI tape drive is <filename>/dev/st0</filename>. Use the appropriate device path for your system.
|
|
|
|
|
Az alapértelmezett eszköznév SCSI szalagos meghajtó esetén a <filename>/dev/st0</filename>. Ehelyett a rendszerének megfelelő eszközútvonalat használja.

Restoring from a tape drive is basically the same as restoring from a file. Simply rewind the tape and use the device path instead of a file path. For example to restore the <filename>/etc/hosts</filename> file to <filename>/tmp/etc/hosts</filename>:

|

A szalagos meghajtóról való helyreállítás alapvetően ugyanaz, mint a fájlból történő. Egyszerűen tekerje vissza a szalagot, és a fájlútvonal helyett használja az eszközútvonalat. Az <filename>/etc/hosts</filename> fájl visszaállítása például a <filename>/tmp/etc/hosts</filename> helyre:
