[quote]Windows Home Server Drive Extender – a file-based replication system that provides three key capabilities:

I have to disagree with you on this one and maybe it was just an oversight with your understanding of how WHS does it. WHS has folder duplication, which [b]IS[/b] backup. It is not a RAID implementation, but simply a duplicate copy stored on [i]another[/i] drive, which is the critical piece. This is precisely the type of backup solution users [i]should[/i] implement.
