This suggests to me that the scheduling is off. It could be due to 
incorrectly staggered cron jobs or runs overlapping. Overlaps /will/ 
wreck the rotation cycles so it's important not to set your backup runs 
too close together. Despite the name, the "hourly" increments aren't 
necessarily hourly; I typically run them 3-6 hours apart.

Tedious, like I originally wrote. :/

I discovered this the hard way. It's more reliable if each node runs its 
own installation and pushes to a unique directory on the backup target. 
Trying to glom many nodes together in a single rsnapshot run is not a 
good way to do it.
