[SOLVED] Create copy of Raspberry PI SD-Card

sudo fdisk -l

Take note of how the SD card is identified.

In my case it is /dev/sdb1.

Then:

sudo dd bs=4M if=/dev/sdb | gzip > /home/your_username/image`date +%d%m%y`.gz

This will compress the image using gzip.

To restore the backup on SD card:

sudo gzip -dc /home/your_username/image.gz | sudo dd bs=4M of=/dev/sdb
