Help Center/ Host Security Service/ API Reference/ API Description/ Ransomware Prevention/ Querying the Backup Policy Bound to HSS Protection Vault

Querying the Backup Policy Bound to HSS Protection Vault

Function

This API is used to query the backup policy bound to the HSS protection vault. Ensure that a ransomware protection vault has been purchased in CBR. Such a vault is named in the HSS_projectid format.

Calling Method

For details, see Calling APIs.

URI

GET /v5/{project_id}/backup/policy

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID

Table 2 Query Parameters

Parameter

Mandatory

Type

Description

enterprise_project_id

No

String

ID of the enterprise project that a server belongs.

An enterprise project can be configured only after the enterprise project function is enabled.

Enterprise project ID. The value 0 indicates the default enterprise project. To query servers in all enterprise projects, set this parameter to all_granted_eps. If you have only the permission on an enterprise project, you need to transfer the enterprise project ID to query the server in the enterprise project. Otherwise, an error is reported due to insufficient permission.

Request Parameters

Table 3 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

User token.

It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is a token.

region

Yes

String

Region ID

Response Parameters

Status code: 200

Table 4 Response body parameters

Parameter

Type

Description

enabled

Boolean

Whether the policy is enabled

id

String

Policy ID

name

String

Policy name

operation_type

String

Backup type. Its value can be:

  • backup

  • replication

operation_definition

OperationDefinitionInfo object

Policy attribute. Reserved rule.

trigger

BackupTriggerInfo object

Backup policy scheduling rule

Table 5 OperationDefinitionInfo

Parameter

Type

Description

day_backups

Integer

Maximum number of retained daily backups. The latest backup of each day is saved in the long term. This parameter is not affected by the maximum number of retained backup. The value ranges from 0 to 100. If this parameter is specified, timezone must be configured. Minimum value: 0. Maximum value: 100

max_backups

Integer

Maximum number of automated backups that can be retained for an 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. If this parameter and retention_duration_days are left blank at the same time, the backups will be retained permanently. Minimum value: 1. Maximum value: 99999. Default value: -1

month_backups

Integer

Maximum number of retained monthly backups. The latest backup of each month is saved in the long term. This parameter is not affected by the maximum number of retained backup. The value ranges from 0 to 100 If this parameter is specified, timezone must be configured. Minimum value: 0. Maximum value: 100

retention_duration_days

Integer

Duration of retaining a backup, in days. The maximum value is 99999. If the value is set to -1, backups will not be cleared even though the configured retention duration is exceeded. If this parameter and max_backups are left blank at the same time, the backups will be retained permanently. Minimum value: 1. Maximum value: 99999. Default value: -1

timezone

String

Time zone where the user is located, for example, UTC+08:00. Set this parameter only after you have configured any of the parameters day_backups, week_backups, month_backups, and year_backups.

week_backups

Integer

Maximum number of retained weekly backups. The latest backup of each week is saved in the long term. This parameter can be effective together with the maximum number of retained backups specified by max_backups. The value ranges from 0 to 100. If this parameter is specified, timezone must be configured.

year_backups

Integer

Maximum number of retained yearly backups. The latest backup of each year is saved in the long term. This parameter can be effective together with the maximum number of retained backups specified by max_backups. The value ranges from 0 to 100. If this parameter is specified, timezone must be configured. Minimum value: 0. Maximum value: 100

type

String

Scheduler type. Currently, only time can be configured.

properties

BackupTriggerPropertiesInfo object

Scheduler attribute

Table 7 BackupTriggerPropertiesInfo

Parameter

Type

Description

pattern

Array of strings

Scheduling policy. The value contains a maximum of 10,240 characters and complies with iCalendar RFC 2445. However, only FREQ, BYDAY, BYHOUR, and BYMINUTE are supported. FREQ can be set to only WEEKLY or DAILY. BYDAY can be set to the seven days in a week (MO, TU, WE, TH, FR, SA and SU). BYHOUR can be set to 0 to 23 hours. BYMINUTE can be set to 0 to 59 minutes.
