Tob is a simple yet configurable shell-script which, given a set of `volume definitions', runs tar or afio based backups, either for use with tape drives or floppy disks. you could also mount and unmount partitions for backups in the pre- and post-commands. tob is a general driver for the making and maintaining of backups. it makes full backups, differential backups (of the files which were changed since the last full backup), incremental backups (of files changed since all previous backups), lets you determine the size of the backup before actually making it, maintain listings of made backups, make remote backups and possibly more.
