CreatePolicyBindings - Cloud Backup - Alibaba Cloud Documentation Center

Binds one or more data sources to a backup policy.

Operation description

You can bind data sources to only one policy in each request.
Elastic Compute Service (ECS) instances can be bound to only one policy.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Source	string	No	If the SourceType parameter is set to OSS, set the Source parameter to the prefix of the path to the folder that you want to back up. If you do not specify the Source parameter, the entire bucket (root directory) is backed up. If the SourceType parameter is set to ECS_FILE or File, set the Source parameter to the path to the files that you want to back up. If you do not specify the Source parameter, all paths backed up.	backup/
Include	string	No	This parameter is required only if you set the SourceType parameter to ECS_FILE or File. This parameter specifies the type of files to be backed up. All files of the specified type are backed up. The value can be up to 255 characters in length.	[\".doc\",\".xltm\"]
Exclude	string	No	This parameter is required only if you set the SourceType parameter to ECS_FILE or File. This parameter specifies the type of files that do not need to be backed up. No files of the specified type are backed up. The value can be up to 255 characters in length.	[\".doc\",\".xltm\"]

Separate multiple throttling rules with vertical bars (\|). The time ranges of the throttling rules cannot overlap. start: the start hour. end: the end hour. bandwidth: the bandwidth. Unit: KB/s.	0:24:1024
AdvancedOptions	object	No	The advanced options.
UdmDetail	object	No	The advanced options for ECS instance backup.
ExcludeDiskIdList	array	No	The IDs of the disks that do not need to be protected. If the DiskIdList parameter is not empty, this parameter is ignored.
	string	No	The ID of the disk that does not need to be protected.	d-bp1************apo

	string	No	The ID of the disk that needs to be protected.	d-bp1************apo
SnapshotGroup	boolean	No	Specifies whether to create a snapshot-consistent group. You can create a snapshot-consistent group only if all disks are Enterprise SSDs (ESSDs).	true

InventoryId	string	No	The name of the OSS inventory. If this parameter is not empty, the OSS inventory is used for performance optimization. If you want to back up more than 100 million OSS objects, we recommend that you use inventory lists to accelerate incremental backup. Storage fees for inventory lists are included into your OSS bills. A certain amount of time is required for OSS to generate inventory lists. Before inventory lists are generated, OSS objects may fail to be backed up. In this case, you can back up the OSS objects in the next backup cycle.	oss-inventory-default
