Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
indices	No	String	Name of an index to be restored. Multiple indexes are separated by commas (,). By default, all indexes are restored. You can use the combination of a backslash and an asterisk () to back up data of certain indexes. For example, if you specify 2018-06, then the data of the indexes with the prefix 2018-06 will be restored.The value can contain 0 to 1,024 characters. Uppercase letters, spaces, and the following special characters are not allowed: "\<\|>/?The default value is *, indicating that all indexes are restored.
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.
frequency	No	String	Frequency of automatically creating snapshots. NOTE: The default value is DAY. If this parameter is set to HOUR, the scheduled task is executed every hour. 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.
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. By default, snapshot creation starts from the next hour after the settings are successful.
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.
