You need to practice restoring your databases so when it becomes necessary in your live network, you'll be prepared to do it right.
It's important to back up your databases, but it's even more important to be able to restore it, so once you've identified how you're going to back it up, make sure you test the different recovery scenarios.
Broadly speaking, there are two database types considered here, traditional and modern, and recovery is different for each. A traditional database in this context is a database that runs in a single server or virtual machine that you manage, and a modern database might run across many nodes or it might even be serverless, where you have no access to the underlying infrastructure.
