Scenario
There are two OpenStack clouds available OpenStack Cloud A and OpenStack Cloud B". OpenStack Cloud B is the disaster recovery restore point of OpenStack Cloud A and vice versa. Both clouds have an independent NetBackup for OpenStack installation integrated. These NetBackup for OpenStack installations write their Backups to NFS targets. "NetBackup for OpenStack A" is writing to "NFS A1" and "NetBackup for OpenStack B" is writing to "NFS B1". The NFS Volumes used are getting synced against another NFS Volume on the other side. "NFS A1" is syncing with "NFS B2" and "NFS B1" is syncing with "NFS A2". The syncing process is set up independently from NetBackup for OpenStack and will always favor the newer dataset.
This scenario covers the disaster recovery of a single policy and a complete Cloud. All processes are done be the OpenStack administrator.
