Perhaps you may want to ditch anacron, and look into launchd?  Lingon  
can be used, I believe, in the same way to shied you from the  
intricacies of OS X scheduling.

If you are able to run interactively your rsync script, which I assume  
asks you for a password to login, then anacron, or launchd are both  
going to need keys on the server no matter what.

Somewhere, you have to have the keys to do a passwordless login.  If  
your machine is compromised, you can always revoke the keys quickly.   
Reading a little about anacron, I can not see there being anything  
launchd can not do, and much more.

Curious also, make sure you use rsync correctly, if you are syncing  
mac files, there are special flags you need to add in order to not  
nuke your Mac OS X resource/data forks, thereby breaking your files  
and having an incomplete backup.

Hope this is a little helpful, not entirely the answer you were after,  
but something I think in the end you will be more happy with.
