By using object storage, data can be migrated to database clusters in different container environments. Even if it is difficult to operate in a container environment with a database cluster deployed due to a disaster, etc., it is possible to continue operation in a different container environment.

Available disaster recovery methods include the backup/restore method and the hot standby method.

Build a new container environment after a disaster (cold standby) and restore data from object storage. Compared to the method described later, this method does not require the construction of two container environments, so it is possible to keep costs down. It takes recovery time to execute.

Before a disaster occurs, start the container environment of the production environment and the container environment of the disaster recovery environment. By implementing disaster recovery in a hot standby configuration, business systems can be restored more quickly in the event of a disaster.

You can also use Velero to back up a system in a Kubernetes environment to object storage for disaster recovery that restores the system to a different Kubernetes.
