DR Management
- Restoring Data from Backup Copies
In the CDM solution, a large number of backup copies are stored on the local and remote storage devices as required. In the case of logical corruption of data, you can flexibly select backup copies to restore data. The use of snapshot technology frees the system from backup software and allows full recovery with higher efficiency. Recovery from a local backup copy can be completed within seconds.
- Reusing Backup Copies
User data increases as businesses grow. The copy reuse function provided by the CDM solution allows users to mining larger value of data directly on DR systems. During copy reuse, level-2 copies are generated based on snapshots and are used for other purposes such as data analysis and test. This does not change the original snapshots. The original snapshots can be used for data recovery. Moreover, changes to snapshots and level-2 snapshot copies do not lead to mutual impact, making operations more flexible.
- DR Test/Clearance
After the DR environment is configured, periodic tests can improve the reliability of the DR environment and avoid configuration problems and environment changes which cause the DR switchover to fail and services not to recover quickly through the DR system. DR tests are implemented using snapshot mappings at the DR site to verify the availability of data or snapshots replicated to the Remote DR center. The test process has no adverse impact on the production site. After a test is complete, the test data generated at the DR site needs to be cleared and resources need to be restored to the status before the test to facilitate future DR or planned migration.
- DR Drilling
To verify the reliability of the DR system, customers usually perform planned DR drills every year or half a year to switch some services in production centers to DR centers. The CDM solution provides the planned migration function for this type of planned switchover.
- DR Switchover
When a disaster occurs at the production end, services cannot be recovered in a short period of time and the production stops. As a result, services must be recovered as soon as possible to avoid greater loss. In the CDM solution, data at the DR site can continue to provide services for the production. After users decide to switch services to the DR center, they can implement one-click recovery at the DR center using underlying applications.
