Modifying Backup Tasks

Updated at: Aug 17, 2021 GMT+08:00


You can modify the parameters of a created backup task on MRS to meet changing service requirements. The parameters of restoration tasks can only be viewed but cannot be 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.
  • You have synchronized IAM users (on the Dashboard tab page, click Click to synchronize on the right side of IAM User Sync to synchronize IAM users).

  1. On the cluster details page, choose Backups & Restorations > Backups.

    For MRS 3.x, see Modifying a Backup Task.

  2. In the task list, locate a specified task, click Modify in the Operation column to go to the configuration modification page.
  3. Modify task parameters on the page that is displayed.

    • The following parameters can be modified for manual backup:
      • Target Path
      • Max Number of Backup Copies
    • The following parameters can be modified for 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.
