Scripting & Automation (Raspberry Pi 5) · Backup to NAS Server
Backup to NAS Server
Automate backups from Raspberry Pi 5 to a Raspberry Pi 3 NAS with SSH keys, proper permissions, an rsync-based Bash script, and weekly scheduling via cron.
Goal: back up the Automation directory from the Pi 5 to a Pi 3 NAS. Steps: generate SSH keys → copy the public key to the NAS → confirm key-based login → set directory permissions → write the backup script → make it executable → run it → verify on the NAS → schedule weekly.
1) Generate SSH key pair
2) Copy the public key to the NAS
3) Confirm key-based SSH login
4) Verify user context with whoami.
5) Grant write permissions on NAS path
Ensure the user referenced by the script can write to /mnt/nasdrive on the NAS.
6) Write the backup script
Open nano and create the script: set variables, check directory access, run rsync with logging, and print success/fail status.
7) Make the script executable
8) Run the script
9) Verify on the NAS
10) Schedule weekly via cron
