Can an Apple Software RAID Mirror drive be transferred?
on Aug 10, 2010 at 2:09:35 pm

Hi all.

I work at a small production company and I'm trying to figure out a cost effective way to keep up with the increasing amount of data we need to make sure is contantly backed up. I was wondering if I had an Apple G5 with three hard drives set up in the following configuration:

Drive 1 - System Drive (time machine backup to external drive)
Drive 2 + Drive 3 software RAID mirror to use as 'work' drive

...in the event of failure of drive 2 or 3, would it be possible to take out the other and just put it straight into another G5 to access the data? I heard that Apple Software RAIDs only work in the system they were created in or does that not apply if it's a mirror RAID?

You might try asking this question in the Arrays and RAID Setup forum.

EDIT: Sorry, you are here already -- it was me who was lost!

Since I've mistakenly commented in this thread already, maybe I can try to be helpful. I don't know the answer to your question, but if you're looking for a live backup on a Mac, you might consider using Time Machine instead of a soft RAID.

Both would offer protection against the failure of the drive, but RAID will not offer protection against accidental data loss -- like a file deletion or overwrite. Time Machine does.
