Hi John,

What kind of backup device do you have?

I would suggest you to use a disk copy program(simple tar should be enough) to take dump of entire hard disk and move it to other location.

If you have enough work experience in Linux then what you have to do is:

* Boot the system with a rescue CD (use the first CD of RH 2.1 and type 'linux rescue' at the boot prompt. It will drop you in to a root shell

* Enable network on the system with the IP. Have some free space available on a remote server (preferrably linux)

* Then mount first local Linux partition, make tar dump of the partition using 'tar -zcvf tar-file.tar.gz /partition/mountpoint'

* Transfer this dump to the remote system (either mount the remote machine partition to local system by NFS or SAMBA etc).

* Do the above for all available partitions.

* Then exit, and reboot the machine and do whatever you want to do with the RAID. After that boot back with linux rescue CD.

* Now you will have new enhanced hard disk, create partitions similar to your old setup (size can be different) but the name and number of partitions should be same.

* setup the network, connect with the remote machine

* Transfer each tar backup file one after other and extract them to the local partition by 'tar -zxvf tar-file.tar.gz'

* Run grub or lilo boot loader and the root partition and there you go, you should have your new system up and ready.

If you are not so experienced on linux, then there are applications which can do this for you:
* HP's Rapid Deployment Pack which can take image of a system
* Ghost for Linux
* Mondo rescue CD


Hope this helps,
Gopi
