Clone your Raspberry Pi SD card

Tweet

Once you have your Raspberry Pi setup just the way you like, it would be a shame to lose all that work because the SD card became corrupted.

This is how to make backup copy of the entire SD card on your computer.

(Note: This is the followup to my other post: Create SD card for Raspberry Pi using command 'dd'

• Shut down your RPi
• Remove the SD card and insert it into your computer
• Unmount all partitions using: 

sudo umount /dev/sdb1
sudo umount /dev/sdb2

• Copy the SD card into an image file using:  

sudo dd bs=4M of=<your_image filename.img> if=/dev/sdb

• Wait about 10 minutes while it copies
• Re-insert the card in your Raspberry Pi knowing your data is backed up
