- any configuration to the cluster introduced by manual changes (e.g. changes that weren't saved under the <data-dir>/manifests)

The backups created by k0s backup command have following pieces of your cluster:
|

- certificates (the content of the <data-dir>/pki directory)
|

- etcd snapshot, if the etcd data store is used
|

- Kine/SQLite snapshot, if the Kine/SQLite data store is used
|
|
- k0s.yaml

- any custom defined manifests under the <data-dir>/manifests
