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 backup path and interval are configurable from the U/I during cluster creation OR using the Edit Cluster option on existing clusters.
