Introduction to recovery plans of OceanStor ReplicationDirector

If data or applications at a production site become unavailable due to disasters or faults, you need to recover data from a disaster recovery site. Fault recovery is performed only in the disaster recovery management system at the disaster recovery site. The latest backup data at the disaster recovery site is used to recover data.

If data or applications at a production site need to be recovered from a disaster recovery site due to a power failure, upgrade, or maintenance, you need to perform planned migration at the disaster recovery site. The latest data changes at the production site will be synchronized to the disaster recovery site. Planned migration is performed only in the disaster recovery management system at the disaster recovery site.

In OceanStor ReplicationDirector (current major version: V100R003C10), the recovery plan states include: 1. Test Ready, Testing, Test failed, or Tested. 2. Clearance Ready, Clearing, Clearing failed, or Cleared. 3. Planned migration Ready, Migrating, Migration failed, or Migration complete. 4. Reprotection Ready, Reprotecting, Reprotection failed, or Reprotection complete. 5. Fault recovery Ready, Fault recovering, Fault recovery failed, or Fault recovery complete. 6. Execution Ready, Rolling back, Rollback failed, or Rollback complete.

You can test a recovery plan to verify the availability of the data replicated to the disaster recovery site. During a test, the disaster recovery site generates test data using snapshots, which does not have any impact on the production site. After the test is complete, the test environment must be cleaned up. Before a failover or planned migration, at least one recovery plan test must be executed successfully. The test can be performed only in the disaster recovery management system at the disaster recovery site.

OceanStor ReplicationDirector (current major version: V100R003C10) provides two types of recovery plans: 1. Local recovery plan Based on a snapshot protection policy template, a local recovery plan is executed to roll back data. 2. Remote recovery plan Based on a remote replication protection policy template, a remote recovery plan is executed to perform planned migration or fault recovery.
