When using a tape drive the filename portions of the script aren't needed because the date 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.

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>:
