Back Up Raspberry Pi OS To Image

less than 1 minute read

After install and configure many things on my Raspbery Pi, it will be too much if I have to do it again. Backing it up is really a good idea.

I need A SD card reader and a computer with Linux on it. Insert the card into the card reader, plug it into the computer. Find out where the id of the SD card using this command:

df -h

Mine is /dev/sdb.

Backup it

Navigate to where you want to save the image, then:

sudo dd bs=4M if=/dev/sdb | gzip > rasbian.img.gz

Note: gzip is for compressing the image to a managable size.
