How To Identify the Master Node With Latest ETCD Backup

Problem

How to identify which Master node has the latest ETCD backup/snapshot?

Environment

Platform9 Managed Kubernetes - All Versions
ETCD

Procedure

The backup is run on only one of the master nodes part of the cluster. You can identify the master node on which the recent backup was completed successfully. The output will give you the NodeIP/Nodename on which the most recent backups are stored.

The default backup path is /etc/pf9/etcd-backup. The backup path and interval are configurable from the U/I during cluster creation OR using the Edit Cluster option on existing clusters.
