Modifying a Backup Task

Scenario

Impact on the System

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

Prerequisites

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

Procedure

  1. On FusionInsight Manager, choose O&M > Backup and Restoration > Backup Management.
  2. In the task list, locate a specified task, click Configure in the Operation column to go to the configuration modification page.

    On the displayed page, modify the following parameters:

    • Started
    • Period
    • Destination NameService Name
    • Target NameNode IP Address
    • Target Path
    • Maximum Number of Backup Copies
    • Maximum Number of Recovery Points
    • Maximum Number of Maps
    • Maximum Bandwidth of a Map

    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.
