Recover Lost Data from Replica

The following procedure is the same for all server types.

To recover all lost data from a Replica

  1. On the Manager, select the desired scenario from the Scenario pane and stop it.
  2. (For database applications only) Stop the database services on the Master host.
  3. On the Manager, select the Replica host from the scenario folder. If multiple Replicas participate in a scenario, select the one from which you wish to recover data. The Restore Data option is now enabled.
  4. From the Tools menu, select Restore Data or click the Restore data from the Standard toolbar.

    Note: If the user credentials you used to log in to the Manager are different than the ones required for working with the Engine on the Replica, a User Credentials dialog opens, asking you to enter logon account details for the selected Replica.

    The Recovery Method page of the Restore Data wizard appears.

    Note:  If the Data Rewind property is set to On, another Restore Data dialog will appear. In this case, select the first option - Replace all data on Master with the data on Replica. This option simply restores data without a rewind.

  5. Click Next. The Synchronization Method page appears.
  6. Make sure that the appropriate Synchronization method is selected. For more details, see the Arcserve RHA Administration Guide. Click Finish.

    Once you finished initiating the recovery process, Arcserve RHA builds a temporary reverse tree using the selected Replica as the root, and the Master as the terminating node. After the Master recovery process ends, the temporary scenario is deleted, and you receive the following message in the Event pane: Synchronization finished.

    Note: If an error occurred during the temporary Recovery scenario run, the Recovery scenario may stop and remain in the Scenario pane. In this case, you should remove it by right-clicking it and selecting the Remove option from the pop-up menu. After the Recovery scenario is removed, the original scenario re-appears in the Scenario pane. Then, you can restart the original scenario, and repeat the recovery process if necessary.

  7. By default, once a data recovery occurs a Synchronization Report is generated.

    Now, the replication process can restart following the original scenario.
