Which files are the Time Machine backups?

Hey all,

I'm in the process partitioning my backup drive so that I have one partition as a bootable OS and a bigger partition for my Time Machine backups. I made the mistake of setting up Time Machine on the drive after already installing OS X on it and not partitioning a separate Time Machine partition.

My question is, are the only files Time Machine uses in the backups folder? Or is there something else I should make sure not to erase when I make the transfer to the partition?

 

Perfect, that's exactly what I needed to know. Thanks!
