5.11.2 Disaster Recovery with Continuous Recovery Method

5.11.2.1 Disaster Recovery Prerequisites

When performing disaster recovery using the continuous recovery method, the database cluster must be configured based on the "4.14.3.1 Defining a Continuous Recovery Method". At this time, it is necessary to periodically back up the database to object storage.

5.11.2.2 Performing Disaster Recovery

In the event of a disaster, the FEPCluster in the disaster recovery environment should be promoted.

Describes the procedure for promoting a FEPCluster in a disaster recovery environment deployed in a hot standby configuration. If the production environment becomes unusable when a disaster occurs, you can promote the disaster recovery environment to the production environment by executing FEPAction(promote_standby).

An example FEPAction definition is shown below.

  name: new-fep-promote-standby-action
  namespace: my-namespace
spec:
  fepAction:
    type: promote_standby
  sysExtraEvent: true
