Hi everyone, I'm running a server with ISPConfig and the websites' files and databases are locally backed up under /var/backup. In case of a major issue with my main hosting, I need to recursively grab what's there to store it on a backup server elsewhere. I found the easiest way to do just that was to run a cron from the backup server: Code: 30 4 * * 2 scp -i ~/.ssh/id_rsa -r [email protected] So, while this is working just fine and it's easy to operate, there is an inherent safety issue here. If somehow my backup server is hacked, that key being used to run the SCP command gives root access to the main server. That's not the best option and defeats the purpose of an external backup. What would you say are my options here, if any? How can I secure the access to the main server from the external backup server? My understanding is that files in /var/backup are accessible from root only on the main server. Your feedback on this is more than welcome, thank you.
