Our product dependency on the Kubernetes cluster is growing steadily and it may well be the case that an accident might happen at any moment where the cluster/resource may be deleted by an administrator.

What is the easy way to back up the cluster in a way that it could be restored quickly if an unfortunate event occurs?

Currently, we maintain a batch script which backs up all the named resources. The CD pipelines are set from git repositories- so, recreating workloads is not the case.

We are worried about setting up namespaces, ingress, etc quickly.
