crap.
just had a big long post typed and I think I hit control-r instead of shift-r.
Anyways, let's try this again:
If your desktop Raid is transparent to the OS, then maybe, though I think restoring an individual drive is beyond it's capabilities. You would need to put a third drive in and let it restore the whole image.
WHS does not support Raid, though again if it is hardware level and just presents a drive to the WHS it can work. In my personal view on it, I would only Raid the system drive of a WHS, and let the folder duplication handle the rest, this way you still have data on redundant disks, expansion is easier over time, and they are standard NTFS volumes you can pop into another computer if you ever needed to.
It won't back up the linux machine.
WHS is quite good but it definitely depends on the individual and their demands. I use ours for:
nightly backup of 4 W7 machines. Have done successful restores over the network twice.
Ripping all of our DVDs and CDs to it. Using My Movies which also runs on the HTPC and handles transcoding to the MCX.
Storing utilities, install programs, drivers, documents pics etc.
Recorded tv gets dumped there periodically.
No need for remote access so I have it disabled but have tried it out successfully to test it.
Folder duplication lets you pick and choose, for example I have the music duplicated, recorded tv isn't, and dvds will be eventually. Instead of the RAID approach of duplicating everything.
Also, beyond just making the images for backup, you can open any of your saved backups and it will let you browse the drive. So when you delete that important paper or presentation, you can go back and find the copy you had on disk last night.
Hope this helps.
