Question: Kubernetes docs says that ETCD backup can be made simply by copying the live backup file. Can this be used in the exam as it is quicker option?
Built-in snapshot
etcd supports built-in snapshot. A snapshot may either be taken from a live member with the etcdctl snapshot save command or by copying the member/snap/db file from an etcd <Configuration options | etcd directory> that is not currently used by an etcd process. Taking the snapshot will not affect the performance of the member.
