Hi all. I have a MacBook Pro and I've come to the conclusion that I need to do a fresh installation to solve several problems I've been having. My question involves my Time Machine backup. I have a complete, current backup on a USB drive.


After I do the fresh installation, rather than copy everything from the backup (and possibly bringing the problems with it) I would like to just selectively restore certain things. I know how to do all this.


The question I have is, after I set up my new system, what will happen if I activate Time Machine and point it to the same USB drive that has my current backup? Will it erase the backup, or will it create a new backup alongside the old one (there's plenty of room on the drive) or will it simply append the backup, treating it just like a new checkpoint in the incremental backup? I guess I'm hoping for the third option, because then I would be able to go back into Time Machine in case I forget something or want to copy something from my old system, even after I finish setting up the new one.


Any help would be greatly appreciated.

MacBook Pro (15-inch Early 2011), Mac OS X (10.7.4)
