Hi Kevin,
I haven't tried this with linux, but I have seen SFTIII running on netware
- if it follows the same principles then...
Just a word of caution. Hardware redundancy is not a replacement for a
good backup. It just means you're protected against hardware failure. If
you're mirroring a live file system and an important file gets screwed up,
it's screwed up on both systems.
