time machine on main hard drive

[r9thomas]

Hi...I am downgrading from maverick to mountain lion. I do not have an external drive to use time machine the way it was intended, but instead want to use TM to ease this downgrade process.
I created a Partician on my hard drive and had time machine back up to there. Once I run the installer to load mountain lion on another partician, I shouldn't have a problem migrated data from time machine even though its on the same hard drive...correct?
Thanks
Rick

That will work just fine.

Do you mean you have no back up except on the patrician on your internal? That means you have no back up at all. If your drive fails you will lose all your data. Hopefully you at least have cloud back up? Check out the MacRumors guide section for a recent article about cloud options.

Just just install Mountain Lion over the original OS partition, and leave your newly created TM partition.

The restore what you need from there.

Obviously from a backup perspective, it's not a backup if it's on the same disk, but for what you're trying to accomplish, it should be fine.
