Simple RouterBOARD backup tool

How to install it on your own environment

• Fork this repo to your GitHub account (use private repo in usual case or public if you want to show your credentials to the world).

• Clone your forked repo to NOC host (or any machine inside your network which can act like a network operational center).

• Generate and setup on GitHub local deployment key for synchronizing changes on local host and setup email and name for git commiter like:

git config --global user.email "[email protected]"
git config --global user.name "routerbkp"

• Generate new (second) ssh key for special backup user which will deal with saving backups: ssh-keygen -f .ssh/id_rsa -q -N ""

• Optional: encrypt it using SOPS: sops -e .ssh/id_rsa > .ssh/id_rsa.sops and then delete original key rm .ssh/id_rsa

• Add your routers line-by-line to routers.txt list. I prefer to use DNS names rather IP addresses in form router-N.location.mydomain.com. Add :<portnum> if you have custom SSH ports for specific router.

• Add keys and configuration to git repo git add && git commit -m "Configure"

• Run ./add_ruser.sh to add routerbkp and its ssh key to all routers. Use ADMIN environment variable to specify different administrator account (by default used admin).

• Run ./do_backup.sh to make sure that everything will work automatically. Check git log to see commits with full routers configuration.

• Add do_backup.sh as cron job or systemd timer (see hints below). Check later that eventually configuration changes will appear in your GitHub repository.

Add systemd timer

mkdir -pv ~/.config/systemd/user/
cp timers/routerbkp.* ~/.config/systemd/user/
systemctl --user enable routerbkp.timer
systemctl --user start routerbkp.timer
systemctl list-timers --all --user
