Modifying Backup Tasks¶
Scenario¶
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.
Prerequisites¶
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 page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)
Procedure¶
On the cluster details page, choose Backups & Restorations > Backups.
In the task list, locate a specified task, click Modify in the Operation column to go to the configuration modification page.
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
Note
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.
Click OK.
