Quick script to back up contents of a remote Raspberry Pi
This script uses a passwordless method to authenticate to the Raspberry Pi, this is so you don't have to worry about password prompts.
Copy your public SSH key, usually located at ~/.ssh/id_rsa.pub.
On your Raspberry Pi, if the following file or directory doesn't exist, make it. ~/.ssh/authorized_keys
Paste the public key at the end of the authorized_keys file. This will allow you to securely SSH without a password.
If you have random issues running this script after a copy/paste, try this command on the script: sed -i -e 's/^M$//' RPi_Backup.sh
You'll need to modify the script to point to the correct IP address of the Pi you're trying to backup:
ssh [email protected] <-- Change this IP address and username if you are not using the pi user.
Replace what I have in the dd of= portion with the filepath of where you'd like to store the Pi backup.
