  Parameter	Mandatory	Type	Description
  app_consistency	No	Integer	Whether to perform application-consistent backup on backup objects associated with the backup policy. Possible values are 0 (no), 1 (yes, and stop backing up data after the application-consistent backup fails), and 2 (yes, and continue to perform crash-consistent backup after the application-consistent backup fails). If app_consistency is not specified, application-consistent backup will not be performed. For details about the application-consistent backup feature, see the description in section "Creating a Resource Backup."

  Table 7 Parameter description of field operation_definition

  Parameter	Mandatory	Type	Description
  max_backups	No	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	No	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.

  plan_id	No	String	Backup policy ID
  provider_id	No	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.

  

  • If permanent is set to true, backups will be retained permanently, despite the settings of max_backups and retention_duration_days.
  • If permanent is set to false, settings of max_backups and retention_duration_days are effective.
  • If none of permanent, max_backups, and retention_duration_days is set, backups will be retained permanently.
• Parameter description of field trigger

  Table 8 Parameter description of field trigger

  Parameter	Mandatory	Type	Description
  properties	Yes	trigger_properties	Scheduler properties For details, see Table 9.

• Parameter description of field trigger_properties

  Table 9 Parameter description of field trigger_properties

  Parameter	Mandatory	Type	Description
  pattern	Yes	String	Scheduling policy of the scheduler. The value consists of a maximum of 10,240 characters. The scheduling policy complies with iCalendar RFC 2445, but it supports only four parameters, which are FREQ, BYDAY, BYHOUR, and BYMINUTE. FREQ can be set only to WEEKLY or DAILY. BYDAY can be set to MO, TU, WE, TH, FR, SA, or SU (seven days of a week). BYHOUR ranges from 0 to 23 hours. BYMINUTE ranges from 0 to 59 minutes. The scheduling interval cannot be less than 1 hour. A maximum of 24 time points are allowed in a day.
