Case: Can I Clone a Raspberry Pi SD Card?

Can anyone help? I have my Raspberry Pi model 3 image on a 16 GB micro SD card. I tried to clone the card to another card but I find that the new card is a few MB smaller!

Raspberry Pi is a series of credit-card sized and single-board computers that plugs into a computer monitor or TV. It enables users to do basically everything you can expect on a desktop computer. Meanwhile, it has been widely used in many areas for its low cost and high portability.

The Raspberry Pi SD card inserted to the board works as hard drive. If it gets corrupted by power outage, overclocking, or some other reasons, you have no choice but to start from scratch, which is quite frustrating.

In this case, you may want to clone the Raspberry Pi SD card to another card for better performance, or keep the copy as a backup. But how can you do that? Is there an effective SD card copier?

If you’ve been using Raspberry Pi for a while, you probably know it’s a finicky little device. Especially when you use Raspberry Pi as a media center or retro gaming station, the SD card would be crashed and corrupted easily. Thus you may lost everything on it. To avoid this tragedy, you could clone the Raspberry Pi SD card to protect the data.

◉ SD card upgrade:

If the Raspberry Pi SD card has insufficient space or poor performance, you can upgrade it to larger one or newer one. In this case, cloning your Raspberry Pi SD card to another is a good way to avoid data loss.
