Hey, sorry it was hacked.

You mention rsync which can be fine. But there are tons of other solutions, many that will have snapshot features. I use borg backup, for instance. https://www.borgbackup.org/

Also, look into scriping your server setup with tools like Ansible or PyInfra. There is always the risk that bad things happen to servers, and when you want a new server it's great to be able to spin things up in a matter of minutes. Tools like these are profesional best practices these days.

In fact, if you have a scripted server setup and a server that doesn't collect data itself you may not even need backups. What is there to backup? Just spin up a new server with your scripts and carry on.
