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.

Operation	Access level	Resource type	Condition key	Associated operation

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	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\"]

OssDetail	object	The advanced options for OSS backup.
InventoryId	string	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.	inventory_test

FetchSliceSize	long	The size of backup shards (the number of files).	100000
SourceType	string	The type of the data source. Valid values: UDM_ECS: ECS instances	UDM_ECS
CrossAccountType	string	Indicates whether data is backed up within the same Alibaba Cloud account or across Alibaba Cloud accounts. Valid values: SELF_ACCOUNT: Data is backed up within the same Alibaba Cloud account. CROSS_ACCOUNT: Data is backed up across Alibaba Cloud accounts.	CROSS_ACCOUNT
CrossAccountUserId	long	The ID of the source Alibaba Cloud account that authorizes the current Alibaba Cloud account to back up data across Alibaba Cloud accounts.	1480************
