I'm curious about the best practices for testing backups. How do you do it? Is there a safe way to restore a production server to another machine without causing any issues? I want to make sure my system state backups are reliable before I need them.

For testing backups, we always do it in an isolated test environment. If you're not using one, restoring directly from production could lead to complications. Every year, we conduct full system state testing during our disaster recovery tests.
We have a dedicated environment that simulates our production setup. We create a fresh VM from a snapshot, use Ansible to configure it, then restore the backup and run predefined tests to check if the application, database, or system is working correctly. After that, we reset the VM to its clean state and repeat the process.

What does an isolated test environment look like, and how do I set one up?
