Parameter description

**Table 1** Parameter description
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.
begin_time	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. NOTE: When end_time is not empty, begin_time is mandatory.

backups	Array of objects	Indicates the backup list. For details, see Table 3.
total_count	Integer	Indicates the total number of records.

**Table 3** backups field data structure description
Name	Type	Description
id	String	Indicates the backup ID.
name	String	Indicates the backup name.
type	String	Indicates the backup type. Value: auto: automated full backup manual: manual full backup fragment: differential full backup incremental: automated incremental backup
size	Long	Indicates the backup size in KB.
status	String	Indicates the backup status. Value: BUILDING: Backup in progress COMPLETED: Backup completed FAILED: Backup failed DELETING: Backup being deleted
begin_time	String	Indicates the backup start time in the "yyyy-mm-ddThh:mm:ssZ" format. 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.
end_time	String	Indicates the backup end time. In a full backup, it indicates the full backup end time. In a MySQL incremental backup, it indicates the time when the last transaction in the backup file is submitted. The format 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.
