I recently set up a FreeBSD 5.3 box running Samba to hold all of our 
Windows users home directories.  I've already had to restore a few 
files from the daily backups because somebody hosed their files in one 
way or another.  Having hourly snapshots like this will be great. 
Currently I will have to set up special Samba access to the snapshot 
area which will make using them a bit harder, but having a '.snapshot' 
directory inside each directory would be ideal.  Great work!
