[DM-MUG] long-term data storage

[Myztik Jenz]

Setting up RAID 1 via Disk Utility is destructive to the existing data
on the drives.  There may be third-party ways to do it, but with Disk
Utility, it'll want clean drives.

And as a side, I use two 250GB drives in a RAID 1 for my backup
storage and I've been happy as a clam with the solution (I backup with
Retrospect to said RAID, so I never directly delete anything from it).
 My only problem is that I'm running out of space...

If not, my plan is to boot with the Tiger install CD, and try to setup a RAID between the internal boot volume and the second internal volume. I'll make a full backup onto an external drive first of course.
