Restoring a DCS Instance

On the DCS console, you can restore backup data to a chosen DCS instance.

You can enable or disable multi-DB for a Proxy Cluster instance. Data backed up when multi-DB is enabled cannot be restored to the instance after multi-DB is disabled.

Prerequisites

  • A master/standby, cluster, or read/write splitting DCS instance is in the Running state.
  • A backup task has been run to back up data in the instance to be restored and the backup task succeeded.

Procedure

  1. Log in to the management console, and choose Application > Distributed Cache Service in the service list.
  2. Click in the upper left corner of the management console and select the region where your instance is located.
  3. In the navigation pane, choose Cache Manager.

    Filter DCS instances to find the desired DCS instance. Currently, you can search instances by name, specification, ID, IP address, AZ, status, instance type, cache engine, and many other attributes.

  4. Click the name of the desired DCS instance to go to the details page.
  5. On the instance details page, click Backups & Restorations.

    A list of historical backup tasks is then displayed.

  6. Click Restore in the row containing the chosen backup task.
  7. Click OK to start instance restoration.

    Information in the Description text box cannot exceed 128 bytes.

    You can view the results of all restoration tasks on the Restoration History page. The records cannot be deleted.

    Instance restoration takes 1 to 30 minutes.

    While being restored, DCS instances do not accept data operation requests from clients because existing data is being overwritten by the backup data.
