Backing up Ubuntu

"LVM

Yet another method would be LVM

    LVM stands for Logical Volume Management. It is a system of
    managing logical volumes, or filesystems, that is much more
    advanced and flexible than the traditional method of partitioning a
    disk into one or more segments and formatting that partition with a
    filesystem.

    Snapshots

    This is something you simply can not do without LVM. It allows you
    freeze an existing Logical Volume in time, at any moment, even
    while the system is running. You can continue to use the original
    volume normally, but the snapshot volume appears to be an image of
    the original, frozen in time at the moment you created it. You can
    use this to get a consistent filesystem image to back up, without
    shutting down the system. You can also use it to save the state of
    the system, so that you can later return to that state if you mess
    things up. You can even mount the snapshot volume and make changes
    to it, without affecting the original." -
