What is this about ?
********************

This is a script to write a backup to a tape. This may be run from cron as a one liner.
One of a great family of these things.

Installation
************

Copy the file TapeBackup to /usr/local/bin and make it executable.
Note that this script uses the Korn Shell (ksh), you may need to install
this on your machine.

*******

A log is written in /var/log/tapebackups/.

    -C dev
    	tape Control device, default /dev/st0

	space separated list of directories to back up, eg:
		-d '/home /root /etc/'
	It is OK if some of the expanded names contain spaces.

    -I
	Incrememtal backup since last complete tape backup.

	The file /arch/<MachineName>/FullTapeBackup is touched with the time
	of the file RsyncBackupSuccessTime. The file RsyncBackupSuccessTime is touched
	by RsyncBackup with the start time of it's backup.
	An incremental backup is for files newer than FullTapeBackup.
