    Are you booted from the backup on an external drive as it does not appear?
    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    The one you want is the indented Mac HD, but as Harry said, you have to be booted from something else. You cannot erase/format the boot drive.

    I thought "clean install" and "from a backup" would be two separate things? Are you trying to do a clean install of Mac OS X and then restore your files from a backup, or are you trying to restore from a Time Machine backup?

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.
