    Name

    Mandatory

    Description

    project_id

    Yes

    Specifies the project ID of a tenant in a region.

    For details about how to obtain the project ID, see Obtaining a Project ID.

    instance_id

    Yes

    Specifies the DB instance ID.

    backup_id

    No

    Specifies the backup ID.

    backup_type

    No

    Specifies the backup type. Value:

    • auto: automated full backup
    • manual: manual full backup
    • fragment: differential full backup
    • incremental: automated incremental backup

    offset

    No

    Specifies the index position. If offset is set to N, the resource query starts from the N+1 piece of data. The value is 0 by default, indicating that the query starts from the first piece of data. The value must be a positive number.

    limit

    No

    Specifies the number of records to be queried. The default value is 100. The value cannot be a negative number. The minimum value is 1 and the maximum value is 100.

    No

    Specifies the start time for obtaining the backup list. The format of the start time is "yyyy-mm-ddThh:mm:ssZ".

    T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. For example, in the Beijing time zone, the time zone offset is shown as +0800.

    NOTE:

    When begin_time is not empty, end_time is mandatory.

    end_time

    No

    Specifies the end time for obtaining the backup list. The format of the end time is "yyyy-mm-ddThh:mm:ssZ" and the end time must be later than the start time.

    T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. For example, in the Beijing time zone, the time zone offset is shown as +0800.
