    Erase and Install.

    Lesson: Don't install preview/beta OS over your original OS when you are relying on that machine.

    +1. I'm going to wait till Lion has been out for 2-3 months and all the 3rd party software I use is compatible with it :D

    I thought this was mandatory information. Come on, why would you ever run a beta on your everyday computer?

    Makes sense to me..

    A backup of what exactly?
    There is no way to downgrade to Mac OS X 10.6 Snow Leopard without a clean install.

    Why not use Finder to just backup all your files and folders you are interested in, then reinstall Mac OS X 10.6 Snow Leopard and then get back the files and folders you were interested in from the backup you made before you reinstalled Mac OS X 10.6 Snow Leopard?

    Back up your data, erase and install SL, re-install your apps and restore your data.

    Don't restore if you did a Time Machine Backup in Lion

    I've just reverted my system back to Snow Leopard, so as others have said you'll need to format and start over fresh, where I went wrong though is that i'd stupidly let Time Machine backup in Lion, and after installing SL I restored all my data from that backup and found it had installed the Lion applications as well i.e. Launchpad etc. In addition to this a lot of my applications would not run, as they gave me a message stating they required OS X 10.7 to operate now.

    So if you're in the same situation, do a clean install and manually copy across your data from your backup.

    I just did this yesterday. Tired of Lion messing up. I get the beta thing, just don't want to deal.

    I have a 1TB drive so I just re-partitioned the drive while running and then installed SL into new, clean partition. Did the complete restore/install from the original disks that came with MBP.

    Next, I did the Software Update thing then ran migration assistant making sure to NOT move Machine and Applications.

    Restarted and then drag copied over the apps I wanted, settings that were missed and did new installs of everything else.

    All told about a day (10-12 hours) and I am now SL and Lion on one drive in my MBP.

    Worth it to do a clean install and not carry anything back. Move them later.
