[plug] Linux backup programs

[Simon Scott]

	Beyond how to do it, does anyone have any statistics of hardware v
software raid on linux?

	Any 'gut feel' ideas of speed? I guess with mirroring on 2 channels
you would double your read speed???

	No. The easiest way to install a machine using RAID 1 is to 
	do a normal install and then set up the RAID. The first time I did
it I 
	followed the instructions at:
	  http://www.linuxdoc.org/HOWTO/Software-RAID-HOWTO.html
	and didn't have any trouble at all. I used Method 2 under section
4.13.

	Make sure you apply the latest RAID patch (the 0.9 series, not the
one in 2.2 
	by default) and I'd stay away from software RAID under 2.4, judging
by the 
	talk Neil Brown gave at linux.conf.au.

	Oh, and lilo in Debian 2.2 does seem to support booting from RAID
out of the 
	box, just put the autodetect option into the kernel.

	Good luck,

	Grahame
