    The best way to do this (assuming you have not already upgraded to Yosemite) is to use either CarbonCopyCloner or SuperDuper to create a bootable clone of your internal drive BEFORE you upgrade.

    Then -- if you're unhappy with Yosemite -- you can just boot from the clone, re-initialize the internal drive, and then "re-clone" the contents of your backup BACK TO the internal drive.
