Modifying a Backup Task

Updated at: Mar 25, 2021 GMT+08:00


This section describes how to modify the parameters of a created backup task on MRS Manager to meet changing service requirements. The parameters of restoration tasks can be viewed but not modified.

Impact on the System

After a backup task is modified, the new parameters take effect when the task is executed next time.


  • A backup task has been created.
  • A new backup task policy has been planned based on the actual situation.


  1. On MRS Manager, choose System > Back Up Data.
  2. In the task list, locate a specified task, click Modify in the Operation column to go to the configuration modification page.
  3. Modify the following parameters on the displayed page:

    • Manual backup:
      • Target Path
      • Max Number of Backup Copies
    • Periodic backup:
      • Started
      • Period
      • Target Path
      • Max Number of Backup Copies
      • When Path Type is set to LocalHDFS, Target Path is valid for modifying a backup task.
      • After you change the value of Target Path for a backup task, full backup is performed by default when the task is executed for the first time.

  4. Click OK.
