| # | |
| # Backup unifi or protect configuration files to a remote server | |
| # You should install first the public key remotely. | |
| # | |
| # To do ssh authentication if you have a Cloud Key Gen2, it is like any other | |
| # debian. Just use "ssh-keygen" and "ssh-copy-id" | |
| # | |
| # To do ssh authentication (with UDM) you need to generate new keys | |
| # due to dropbear keys are not compatible | |
| # $ dropbearkey -t rsa -f /mnt/data/ssh/id_rsa.backup.private | |
| # | |
| # Copy your public key of the generated key, to print the key just: | |
| # $ dropbearkey -t rsa -f /mnt/data/ssh/id_rsa.backup.private -y | grep ^ssh-rsa | |
| # | |
| # Paste the public key in a new line of your "$HOME/.ssh/authorized_keys" of your remote server | |
| # | |
| # After that you should configure this script and copy in your desired path, but remember to | |
| # change the params. By default is configured to be in: /mnt/data/on_boot.d/S99-backnifi.sh | |
| # | |
| # If you do not want protect backups, you should comment line 68. If you do not want unifi | |
| # backups, you should comment line 65. | |
| # | |
| # 1st time exec the script manually | |
| # | |
| # This script do not provide a way to rotate backups, compressing or whatever but it should be | |
| # added easily. | |
| # | |
| # Can't wait to see your customized or improved version of this script! | |
