Configuring the Automatic Snapshot Creation Policy

Function

This API is used to configure automatic snapshot creation. By default, a snapshot is created every day.

Calling Method

For details, see Calling APIs.

URI

POST /v1.0/{project_id}/clusters/{cluster_id}/index_snapshot/policy

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Definition:

Project ID. For details about how to obtain the project ID and name, see Obtaining the Project ID and Name.

Constraints:

N/A

Value range:

Project ID of the account.

Default value:

N/A

cluster_id

Yes

String

Definition:

ID of the cluster for which you want to create snapshots automatically. For details about how to obtain the cluster ID, see Obtaining the Cluster ID.

Constraints:

N/A

Value range:

Cluster ID.

Default value:

N/A

Request Parameters

Table 2 Request body parameters

Parameter

Mandatory

Type

Description

indices

No

String

Definition:

Name of the index to be backed up. The value * indicates all indexes.

Constraints:

N/A

Value range:

N/A

Default value:

N/A

prefix

No

String

Definition:

Prefix of a snapshot that is automatically created, which is manually entered.

Constraints:

N/A

Value range:

Enter up to 32 characters and start with a lowercase letter. Lowercase letters, digits, hyphens (-), and underscores (_) are allowed.

Default value:

N/A

NOTE:
This parameter is mandatory when enable is set to true.

period

No

String

Definition:

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.

Constraints:

N/A

Value range:

N/A

Default value:

00:00 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. This parameter is mandatory when enable is set to true.

keepday

No

Integer

Definition:

Customize the number of snapshots to be retained. 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.

Constraints:

N/A

Value range:

1–90

Default value:

N/A

NOTE:
This parameter is mandatory when enable is set to true.

enable

Yes

String

Definition:

Whether to enable the automatic snapshot creation policy.

Constraints:

N/A

Value range:

  • true: The automatic snapshot creation policy is enabled.

  • false: The automatic snapshot creation policy is disabled.

Default value:

N/A

delete_auto

No

String

Definition:

Whether to clear all the automatically created snapshots when the automatic snapshot creation policy is disabled.

Constraints:

N/A

Value range:

  • true: Delete all automatically created snapshots when an automatic snapshot creation policy is disabled.

  • false: Retain automatically created snapshots when an automatic snapshot creation policy is disabled.

Default value:

false

frequency

No

String

Definition:

Frequency of automatically creating snapshots.

Constraints:

N/A

Value range:

N/A

Default value:

DAY

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.

Response Parameters

Status code: 200

Request succeeded.
