Backing Up the etcd snapshot.db File for Kubernetes Disaster Recovery

To prepare for disaster recovery of your Kubernetes environment, perform periodic backups of the etcd snapshot.db file. First, use the etcdctl utility to get a snapshot of snapshot.db. Then, use the Commvault software to back up the snapshot to an off-host computer.

When you use the Virtual Server Agent (VSA) to protect Kubernetes Control Plane nodes and etcd database. For information, see System Requirements for Kubernetes Access Nodes. Commvault supports a broad range of Linux distributions and releases in combination with the underlying virtualization hypervisor.

If etcd is protected directly with a file system agent installed on the control plane nodes (which is feasible but not recommended), Commvault supports a broad range of UNIX/Linux operating system distributions and releases. For information, see UNIX and Windows File Servers.
