Pausing a DR Task

You can pause the DR tasks if they may cause buffer overflow or network congestion during peak hours.

You can pause the following DR tasks:
  • MySQL->MySQL
  • MySQL->GaussDB(for MySQL)
  • GaussDB(for MySQL)>GaussDB(for MySQL)
  • DDM->DDM

Prerequisites

  • You have logged in to the DRS console.
  • The DR task is running properly.

Pausing a Task

  1. In the task list on the Disaster Recovery Management page, locate the target task and click Pause in the Operation column.
  2. In the displayed Pause Task dialog box, select Pause log capturing and click Yes.

    • When a task is paused, only the replay or capture and replay of incremental data is paused. Before database cutover, stop the task.
    • After you select Pause log capturing, the DRS instance will no longer communicate with the source and destination databases. If the pause duration is too long, the task may fail to be resumed because the logs required by the source database expire. You are not advised pausing a task for more than 24 hours. For details, check the corresponding log configuration.
    • After the task is paused, its status becomes Paused.
    • You can use the resumable transfer function to continue the DR task.
