When you backup, do you want the files and folders on our servers to exactly match your computer, or do you want
to have files that were deleted on your computer, left on our servers? If you want the 'exact' match, then you want
the synchronize option. This will transfer new, changed, and deleted files and folders.
With MyOtherDrive online backup, you do not have to make this choice for your entire backup. You can create more than one Backup Map, and turn synchronize on for one particular Backup Map, and off for another. With MyOtherDrive backup, you have complete archive and synchronize flexibility.
