Drive mirroring - opinion wanted

[Jerry Feldman]

I've installed it, and I'll take a serious look at it.  I'm a bit gun=20

was screwed up because of a virtual machine in the middle of my backup=20
tarfile which truncated my recovery in roughly the same time frame.=20
Since I am not running a mission critical server, this might be a good=20
replacement for my own backup script.
