If you made a mistake when changing a configuration item, you need to roll back immediately. ACM supports querying configuration change history and rolling back configurations.
Procedure
Log on to the ACM console, and select a region as needed in the upper-left corner.
In the left-side navigation pane, select Configurations , enter the Data ID or Group of the configuration to be queried, and then click Search.
Matching results appear in the list.
In the search results, select More > Historical Versions on the right side of the target configuration.
The
Historical Versions page is displayed.
Perform the following tasks as needed on the page.
To view the configuration content of a specific version, click Details in the Actions column.
To roll back to a specific version, click Roll Back in the Actions column, and on the Configuration Rollback page, click Roll Back.
Note ACM currently saves change histories of up to 30 days.
