Create etcd backup

This SOP should be followed in the following scenarios:

• When the need exists to create an etcd backup.
• When shutting a cluster down gracefully.

Steps

1. Connect to the admin node for either staging or production. See the inventory ocp for produduction, ocp-stg for staging. The hostname is in the group ocp-ci-management or ocp-stg-ci-management.

ssh <admin-node>

1. Become the ocp administrator user, check the hostvars associated with the host in the previous step.

sudo su <ocp-admin-user>

1. Run the cluster backup script:

~/bin/ocp-etcd-backup

1. This will save an etcd snapshot in the ~/ocp_backups location.

2. These snapshots are taken nightly at 02:00 UTC and rsynced to a backup storage device.
