Sounds to me like you're doing it all wrong either way ...

What is *supposed* to happen is that you have the daemon running on one 
machine and the client on the other - doesn't matter which.

Then the client tells the daemon what files are to be copied, THE TWO 
COMPARE CHECKSUMS, and only the stuff that fails the checksum is copied. 
So if you're doing an incremental backup, network usage and writes are 
kept to a minimum.

I tell people to an in-place backup if they're running on a snapshot 
setup, because again it only writes stuff that has actually changed.

Cheers,
