    Question Clone, bootable, back-up, install ML from SL-Help!
    I want to install ML from SL. Sorry, but never got around (had time) to do L.
    I am knowlegable enough to be dangerous with this kind of stuff; so I'm posting this message is to get confirmation on whether I have it figured out enough to do it myself or should I pay Geek Squad to do it.

    I have
    iMac running OS 10.6.8
    usb WD Elements 2TB ext HD NTFS format

    I want to
    download Mountain Lion
    mount on some other USB device following directions from How to Make a Bootable OS X 10.8 Mountain Lion USB Install Drive

    reformat HD to Mac OS Extended (Journaled) following these directions from WD
    How to partition and format a WD drive on Windows (7, Vista, XP) and Mac OSX

    create two partions (Guid Partition Table) 1 for cloning existing drive, 1 for Time Machine back-up.

    clone using Disk Utility with these directions MAC users - How to Clone Hard Drive Using Restore Option in MAC Disk Utility | Serato.com
    set time machine to back up (?)

    Install ML
    reinstall data from TM back-up

    do second clone of internal drive running ML


    I don't know
    if I need to delete all the data on the internal drive to install ML
    do I need to do a Time Machine back-up in additon to the clone before installing ML
    should I make a new clone of the internal HD with ML installed after checking all is ok, and then reformat the partion again to wipe out the SL clone for the ML clone?
    because I am doing all this for the first time should I fork out the money for CCC or SuperDuper to make these clones and just use TM for incremental back-ups
    Do I need to do a complete back-up with TM after installing ML?

    Thank you for your input about this.

    No you dont, you can install straight over Snow leopard, unless tyou wish to do a clean install


    do I need to do a Time Machine back-up in additon to the clone before installing ML
    No, but it wont hurt to have both backups


    should I make a new clone of the internal HD with ML installed after checking all is ok, and then reformat the partion again to wipe out the SL clone for the ML clone?
    I would just go for a time machine backup once Mountain Lion is installed


    because I am doing all this for the first time should I fork out the money for CCC or SuperDuper to make these clones and just use TM for incremental back-ups
    Time machine is perfectly capable of restoring your mac should anything happen


    Do I need to do a complete back-up with TM after installing ML?
    Let Time machine be your backup once you have everything installed
