Editing a DR Task

Prerequisites

Method 1

1. In the task list on the Disaster Recovery Management page, locate the target task and click Edit in the Operation column.
2. On the Configure Source and Destination Databases page, enter information about the service and DR databases and click Next.
3. On the Check Task page, check the DR task.
   • If any check fails, review the failure cause and rectify the fault. After the fault is rectified, click Check Again.
   • If the check is complete and the check success rate is 100%, go to the Compare Parameter page.
     Note

     You can proceed to the next step only when all checks are successful. If there are any items that require confirmation, view and confirm the details first before proceeding to the next step.

4. On the Confirm Task page, specify Start Time. After confirming that the configured information about the DR task is correct, click Submit.

   Table 1 Task settings

   Parameter	Description
   Start Time	Set Start Time to Start upon task creation or Start at a specified time based on site requirements. NOTE: Starting a DR task may slightly affect the performance of the service and DR databases. You are advised to start a DR task during off-peak hours.

5. After the task is submitted, view and manage it on the Disaster Recovery Management page.
   • You can view the task status. For more information about task status, see Task Statuses.
   • You can click in the upper-right corner to view the latest task status.
   • By default, DRS retains a task in the Configuration state for three days. After three days, DRS automatically deletes background resources, but the task status remains unchanged. When you reconfigure the task, DRS applies for resources again.
   • For a public network task, DRS needs to delete background resources after you stop the task. The EIP bound to the task cannot be restored to the Unbound state until background resources are deleted.
   • For a task that is in the Disaster recovery in progress state, you can use data comparison to check whether data is consistent before and after the disaster recovery.
