RSYNC Disaster

I made a major goof, I was trying to speed up copies of data to a DR
server by using rsync, and I screwed up the master filesystem. I
thought that rsync was unidirectional vice bidriectional.

rsync -avz -e ssh local_dir remote_host:/remote_dir



It first copied everything down to the remote server that it lacked,
then brought back everything that the remote server had that the local
server did not. What a mess......


Is there a way to force rsync to just push in one direction?
Or am I better off using rdist?


Ughhhhh.
