Need to clone an SD card

SD card, the abbreviation of Secure Digital card, is a type of removable memory card used to read and write large quantities of data in a wide variety of mobile electronics, cameras, smart devices, and more. Due to their relatively small size, SD cards have been widely used in our daily life. At the same time, more and more users are paying attention to the data backup of SD cards. The main reasons are as follows.

★ Upgrade or replace SD card

Case: “I have 2GB Micro SD card in my Android and want to upgrade to 4GB. How can I achieve it without losing anything from my 2GB card? I mostly use this card to store images/music and most of the apps.”

As the case shows, the current SD card capacity does not meet the user's needs. And he doesn't want to lose data on his old SD card, the only way is to clone the data from the old SD card onto the new SD card. If you want to replace the problematic SD card with a new SD card, the same is true.

★ Make a backup of the SD card

Case: “I'm running CyanogenMod 7 from an 8GB Micro SD card. I'd like to be able to clone the card so I don't have to go through setup, settings, etc., with a new installation if this card fails. Is there any software that can help me clone this SD card?”

As the case shows, many users choose to clone their SD card mainly for data protection. The SD card itself is small and easy to carry, but it is also easy to lose. If you don’t have a backup of it, the loss of your SD card can't be imagined. Cloning a SD card is the equivalent of backing up it.
