I would like to keep my laptop directory in sync with a network drive I have on my local network. So far the best app I can find to accomplish this is "filesync". The problem with it is it stops responding while coping big files, and if there is network trouble (wireless) I am not confident in the end result. What do other people use to keep directories in sync? I don't want to use a backup software, since I don't want to backup my entire HD (I can re-install apps if it goes down). It seems this should be a fairly simple problem to solve... why can't I find anything good with some basic searches?
