Creating a tar backup onto LS120 laser servo diskettes

These notes provide information on how to create and restore raw tar backups on LS120 laser servo diskettes.

To backup a directory and and subdirectory entries onto LS120 diskettes:

cd /directorytobackup ; tar -cvfk /dev/hdd .

Where /directorytobackup is the directory to backup, and /dev/hdd is the LS120 device.

To restore from this backup:

cd /directorytorestore ; tar -xvfk /dev/hdd .

Where /directorytorestore is the directory to restore to, and /dev/hdd is the LS120 device.

Beware of buggy tar variants

To utilize a laser servo diskette drive for multivolume backups, it is necessary to install the heirloom variant of tar. There is currently a serious bug in gnutar, which prevents a multivolume backup from being restored.
