name	String	Backup policy name The value consists of 1 to 255 characters and can contain only letters, digits, underscores (_), and hyphens (-).
parameters	policy_param	Parameters of a backup policy
project_id	String	Project ID

id	String	Scheduling period ID

Parameter description of field operation_definition

**Table 7** Parameter description of field **operation_definition**
Parameter	Type	Description
max_backups	Integer	Maximum number of backups that can be automatically created for a backup object. The value can be -1 or ranges from 0 to 99999. If the value is set to -1, the backups will not be cleared even though the configured retained backup quantity limit is exceeded.
retention_duration_days	Integer	Duration of retaining a backup, in days. The value can be -1 or ranges from 0 to 99999. If the value is set to -1, backups will not be cleared even though the configured retention duration is exceeded.
permanent	Boolean	Whether backups are permanently retained
plan_id	String	Backup policy ID
provider_id	String	Backup provider ID, which specifies whether the backup object is a server or disk. This parameter has a fixed value. For CSBS, the value is fc4d5750-22e7-4798-8a46-f48f62c4c1da.
