Do I need to backup before I upgrade

Soon I will upgrade my MacBook to Mac OS 10.6. Do I have to backup my all data?

    Seriously,you should keep regular backups. If you've never had a hard drive crash, you have no idea how mcuh of a hassle it is to retrieve your data files. Not to mention costly if you have to take the drive to a professional.
    Time Machine helps a lot with regular backups and it's easy to use. I have a second hard drive connected to my Mac specifically for Time Machine. It works in the background so I don't have to think about it.
    You don't have to do a clean install, or reformat your disk, to upgrade. It's just a good idea to back up all your data anytime you upgrade, just in case .

  • I installed Snow Leopard on a separate freshly formatted partition. During installation, Snow Leopard asked me if I wanted to import my settings, files and/or applications from my older OS partition.

    This gave me the advantage of being able to startup from either OS in case I needed to work in the older OS. It also meant that all my data was left intact on the old partition.

    If your HD is too small for two partitions, consider having an external drive for your old OS, and Snow Leopard on the internal HD. Make sure that the external HD partition is bootable and the old OS works properly on it before installing Snow Leopard on the internal drive.

    Installing Snow Leopard will not affect your data, but using separate partitions or having a backup is wise.
