But i can create another system which is not as heavily powered just for backing up,
that can be arranged for less than the price of a duplicate SCSI RAID card.

Am i wrong in assuming a Linux Software RAID partition (mirror) can be used on any other
Linux Software RAID system that has the right (scsi) interfaces for the disk.

I was hoping to be able to pull a drive and make a quick backup from it because the 
Raid Volume will be too big to put on DVD-R , i was thinking of using an ide harddisk .

I know this has been covered fairly recently but i can't find it in the archive , sorry.
