Restoring a DCS Instance

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

Prerequisites

  • At least one master/standby or cluster 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 status of the backup task is Succeeded.

Procedure

  1. Log in to the DCS console.
  2. Click in the upper left corner and select a region and a project.
  3. In the navigation pane, choose Cache Manager.
  4. Click the name of the DCS instance to display more details about the DCS instance.
  5. On the instance details page, click Backups & Restorations.

    A list of historical backup tasks is then displayed.

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

    Information in the Description text box cannot exceed 128 bytes.

    The Restoration History tab page displays the result of the instance restoration task.

    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.

    If the error "111400104 The DCS instance is recovering from an internal fault. Please try again." is displayed, do not restore the instance data. Provide the error information to O&M personnel.
