How To Backup Your Raspberry Pis Sd Card Img
I noticed that there are not many decent tutorials on how to back up the Raspberry Pi’s SD card image, I’ve decided to create a tutorial myself. :)
##1) Plug in your SD card
Standard.
##2) Find out your SD card number
Hit launchpad and search for Disk Utility and select it
After that, select your SD card.
After selecting your SD card, hit command+i to view more information about the SD card. Inside the window, we can find the disk identifier.
So in my case, it’s actually disk2.
##3) Time for backup!
The actual command is using dd which I learnt from Stackexchange.
Note : Running this command might actually take sometime. So go grab a coffee and come back. :)
dd if=/dev/diskx of=/path/to/image bs=1m
So in my case, I want to save it to the Desktop, hence my command will be something like
sudo dd if=/dev/disk2 of=/Users/stevetan/Desktop/image bs=1m
It actually took 1553 seconds which is approximately 25 minutes to backup my whole SD card.
