**Table 4** CreateClusterBackupStrategyBody
Parameter	Mandatory	Type	Description
period	Yes	String	Time when a snapshot is generated every day. Snapshots can only be generated on the hour. The format is HH:mm z: HH:mm refers to the hour time and z refers to the time zone. For example, 00:00 GMT+08:00 and 01:00 GMT+08:00. NOTE: The default value is 00:00 GMT+08:00. When frequency is set to HOUR, you do not need to specify period.

If this parameter is set to DAY, the scheduled task is executed every day. If this parameter is set to SUN, MON, TUE, WED, THU, FRI or SAT, the scheduled task is executed at the specified day of every week. For example, SUN indicates that the task is executed once every Sunday. The number of retained snapshots depends on the execution frequency and indexes set in the automatic snapshot creation policy. If the execution interval is short or the index data volume is large, the number of retained automatic snapshots may not reach the preset value. Set this value based on actual conditions.
prefix	Yes	String	Prefix of a snapshot that is automatically created, which is manually entered. Enter up to 32 characters and start with a lowercase letter. Lowercase letters, digits, hyphens (-), and underscores (_) are allowed.
keepday	Yes	Integer	Set the number of retained snapshots. The value ranges from 1 to 90. Expired snapshots will be automatically deleted on the half hour. The deletion policy applies only to automated snapshots that are executed at the same frequency as the current automatic snapshot creation policy.
bucket	No	String	Name of the OBS bucket used for backup.
basePath	No	String	Storage path of the snapshot in the OBS bucket.
agency	No	String	IAM agency used to access OBS. If none of the bucket, base_path, and agency parameters are specified, the system will automatically create an OBS bucket and an IAM agency. If the creation fails, you need to manually configure correct parameters.
