i dont have time to play with tapes.. daily changing it..
	- forget one day... and you're hosed

	if you're using tapes for weekly offline backups.. no problem

	find /etc /home /... -mtime -90 -type f | tar zcvf /dev/tape -T -
	( 90 days worth of changes )

i prefer 100GB - 1TB of disks to be backed up to other disks ...
	( tapes are too small for "full backups" and definitely too slow )

	- i do daily, weekly, monthly incrementals

	- i want the backup to be live within a few minutes
	of the main server going down for whatever reason

	- i assume "yesterdays or last weeks" tape/disk/backups is BAD
	and can still receover everything from day before or tonights
	backup ...

	- i want a "hands off backup"... if i go away for vacation
	for a week/month... the systems are still properly backed up 
	( semi-guaranteed )

	- i can lose 2 FULL backups and still recover everything
