With rsync --link-dest, is it possible to determine which files are new?

I agree. Raid is no backup.

I expect your experience is extensive to see that many dual drive RAID1 
failures. Haven't seen one yet myself (knock wood).

Several years ago, I recovered all but a handful of files from a 3-drive 
raid-5 array where 2 drives had failed. Wasn't pretty. Needless to say, 
there were no backups (wasn't my doing).

I know where you're coming from. ;)
