Restore data

ApsaraDB for Memcache provides the data restoration feature to minimize the possible loss caused by misoperations.

1. Log on to the ApsaraDB for Memcache console. On the Instances page, find your instance.

2. Click the instance ID or click Manage in the Actions column to go to the instance details page.

3. In the left-side navigation pane, click Backup and Restoration.

4. On the page that appears, click the Backup Data tab.

5. Find the backup file from which you want to restore data and click Restore in the Actions column.

6. In the dialog box that appears, click OK to restore backup data directly to the original instance. Alternatively, you can click Clone Instance to restore backup data to a new instance. After you verify that the restored data is correct, restore the data to the original instance.

   Note

   Data restoration is highly risky. If you have sufficient time, we recommended that you use the instance cloning feature to restore backup data. The feature allows you to create a pay-as-you-go instance to which data can be restored by using a backup set. After you verify that the restored data is correct, restore the data to the original instance.
