I use rsync to backup a windows server to a windows client and a linux client. It's not super efficient on a windows client but it works good enough. A linux client and windows server is much faster.

I also had NTFS corruption for no apparent reason on 3 separate occasions while using the hard links feature of NTFS running under Windows XP. Running the same concept under Server 2k3 has been fine. Specifically I was getting MFT corruption. It was getting very large (think 10-15GB)

I wasn't very successful using R-Studio to get anything back but wasn't too fussed since it was only a backup. And RAID1 didn't save anything of course either...
