Modifying a Backup Task

Updated at: Apr 28, 2020 GMT+08:00


Modify the parameters of a created backup task on MRS to meet changing service requirements. The parameters of recovery 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.
  • IAM user synchronization has been completed. (On the Dashboard tab page of the cluster details page, click on the right side of IAM User Sync to synchronize IAM users.)

  1. On the MRS cluster details page, click Backups & Restorations > Back Up Data.
  2. In the task list, locate a specified task, and click Modify in the Operation column to go to the configuration modification page.
  3. On the page that is displayed, modify the following parameters:

    • Manual backup:
      • Target Path
      • Max. Number of Backup Copies
    • Periodic backup:
      • Start Time
      • Period
      • Target Path
      • Max. Number of Backup Copies
    • If Path Type of the backup task is Local HDFS, the Target Path parameter is valid when the backup task is modified.
    • After the Target Path parameter of a backup task is modified, this task will be performed as a full backup task for the first time by default.

  4. Click OK to save the settings.
