[Samba] Building two redundant servers without clustering

well, i was also wondering how to build up a very redundant solution for 
my samba installations

at the moment i'm using rsync twice a day to sync about 2TB amount of 
data between two hardware raids (both raid5 with 2 hot spare)

advantage: if filesystem is corrupt on one raid, the other raid is 
normaly not affected

disadvantage: because analyzing data to sync by rsync takes time it's 
senseless to sync every our so you have no realtime backup (only 12h before)

how do you avoid this filesystem issue with drbd? doing rsync every 
night seperatly? i don't know of statistics about filesystem damages
