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

This is an interactive script to write the latest backup to tape.

This is designed to be used with RsyncBackup which will have written
backups for one or more machines under /arch.

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

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


The script writetape should also be copied to /usr/local/bin and made executable.
You may need to tweak it, eg specify the options for the tape device that you have.
This is the script that you tell the end user to run, ie they just type:

	writetape

Edit /etc/sudoers with something like that below. Substitute appropriate user
names and machine name:

	User_Alias BACKUP_ADMINS = john, addw

	BACKUP_ADMINS archive.example.co.uk = NOPASSWD:/usr/local/bin/writetape

You may want a varient of writetape for writing incremental backups.
