Somebody suggested rsync, but why bother? Why take an "almost" solution when you can do it properly? > It seems vinum is the only solution if I want to have drive > mirroring.

The only thing it currently can't do is to mirror the root file system (and yes, I'm working on it). > I never worked with vinum (or ccd) so I wouldn't know.
