By using OSS (pgBackRest) functionality to store backup data in object storage, data can be migrated to a database cluster in a different OCP environment.
Even if it is difficult to operate in an OCP environment with a database cluster due to a disaster, it is possible to continue operating in a different OCP environment.
There are three disaster recovery methods available:
Backup/Restore method
Store backups of production environment data in object storage and restore data from object storage after a disaster.
Continuous recovery method
Create a container environment for production and another one for disaster recovery. Store the production environment data in object storage, and continuously restore to the disaster recovery environment.
Streaming replication method
Similarly to the continuous recovery method, create a container environment for production and another one for disaster recovery. Use streaming replication methods to synchronize data to the disaster recovery environment.
