Sprite can handle rom upgrades great and SPB when I was using it couldnt really handle them at all. That is the main reason I switched.

If you are trying to back up your card though... honestly the quickest way to do it IMO is to use a card reader on your pc and do it with a PC application or even the built in Windows back up utilities. This did when I moved from a 2GB to 4GB and then to a 8GB card. Its fast and you have a copy on your computer if your card crupts or something.
