why is your backup so big is the next question that comes to mind. you could keep track of your media files and backup locally before upload. so then you only have to worry about the code portion of your project.

another way to go would be to use an incremental backup solution. rsync may be.

i guess I'm digressing from the main topic of discussion in this thread. let me reiterate.

hope updating solved it for you. else use either of the other two softwares mentioned above. they are both good.
