backup of 200GB disk is easily backed up onto one or two $80 (
160GB ) disks full backup  ( the disks is on sale at fries )

and yes ... definitely .. backup the backup server !!!!


NAS is NOT a backup system ... its a way to share large amts of data with
lots of servers 
	http://www.Linux-1U.net/Disks/san_nas.gwif.html

RAID is definitely NOT a backup system ...
	- raid1/raid5 protects you against ONE disk failure ..
	- if you lose a 2nd disk of the raid1/raid5 array ( $ 1500 ) than
	you will most likely lost all data on the entire array

http://www.Linux-Backup.net
	- lots of free scripts to backup any way you like

i use just disks for backups ... disks are very reliable when used
and configured properly... 
	- use at least 3 different backup servers/media 

	no tapes ....... too slow to restore from bare metal
	no cdrom/dvd ... too small ... i need TB of backups and storage

	- i want the "backup systems" to be live within 30 seconds
	of a major failure by simply changing its hostname and ip#
 		- but i do NOT want it done automatically ...
		( i want to know what caused the failure first 
		( before i risk my multiple backups 

i use find | tar  .... ( its all free ) and you can tweek it
to the way you want it and i always have a tgz file of what
was copied to backup and when ..
