**Table 4** Response body parameters
Parameter	Type	Description
sync_task_id	String	The synchronization task ID. Minimum length: 0 characters Maximum length: 255 characters
src_cloud_type	String	The source cloud service provider. The value can be AWS, Azure, Aliyun, Tencent, HuaweiCloud, QingCloud, KingsoftCloud, Baidu, Qiniu, or UCloud. The default value is Aliyun. The value can be: AWS Azure Aliyun Tencent HuaweiCloud QingCloud KingsoftCloud Baidu Qiniu UCloud
src_region	String	The region where the source bucket is located. Minimum length: 0 characters Maximum length: 100 characters
src_bucket	String	The name of the source bucket. Minimum length: 0 characters Maximum length: 1,024 characters
create_time	Long	The time (Unix timestamp, in milliseconds) when the synchronization task was created. Minimum value: 0 Maximum value: 9223372036854775807
last_start_time	Long	The last time (Unix timestamp, in milliseconds) when the synchronization task was started. Minimum value: 0 Maximum value: 9223372036854775807
dst_bucket	String	The name of the destination bucket. Minimum length: 0 characters Maximum length: 1,024 characters
dst_region	String	The region where the destination bucket is located. Minimum length: 0 characters Maximum length: 100 characters
description	String	The task description, which cannot exceed 255 characters. The following special characters are not allowed: <>()"'& Minimum length: 0 characters Maximum length: 255 characters
status	String	The synchronization task status. SYNCHRONIZING: a synchronizing status STOPPED: a stopped status The value can be: SYNCHRONIZING STOPPED
enable_kms	Boolean	Indicates whether KMS encryption is enabled. This function is disabled by default.
enable_metadata_migration	Boolean	Indicates whether metadata migration is enabled. The default value is false. Even if this function is disabled, the Content-Type metadata will still be migrated to ensure a successful migration.
enable_restore	Boolean	Indicates whether automatic restoration of archived data is enabled. The default value is No. If this function is enabled, archived data is automatically restored and migrated.
app_id	String	This parameter is mandatory when cloud_type is Tencent. Minimum length: 0 characters Maximum length: 255 characters
monthly_acceptance_request	Long	The number of objects requested for synchronization in the current month. Minimum value: 0 Maximum value: 9223372036854775807
monthly_success_object	Long	The number of objects that were successfully synchronized in the current month. Minimum value: 0 Maximum value: 9223372036854775807
monthly_failure_object	Long	The number of objects that failed to be synchronized in the current month. Minimum value: 0 Maximum value: 9223372036854775807
monthly_skip_object	Long	The number of objects that were ignored in the current month. Minimum value: 0 Maximum value: 9223372036854775807
monthly_size	Long	The total size of synchronized objects in the current month, in bytes. Minimum value: 0 Maximum value: 9223372036854775807
object_overwrite_mode	String	Indicates whether a source object is allowed to overwrite its paired destination object. The default value is SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE. NO_OVERWRITE indicates the system never allows overwriting. The system always skips source objects and keeps their paired destination objects. SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE indicates the system allows overwriting based on the results of size or modification time checks. It is the default setting. If a source object is not as large as or was last modified more recently than its paired destination object, the source object will overwrite the destination object. Otherwise, the source object will be skipped. CRC64_COMPARISON_OVERWRITE indicates the system allows overwriting if the source and destination objects have different CRC64 checksums. This option is only available for migration within Huawei Cloud or from Alibaba Cloud or Tencent Cloud. If a source object has a CRC64 checksum different from the paired destination object, the source object will overwrite the destination object. Otherwise, the source object will be skipped. If either of them lacks a CRC64 checksum in the metadata, their sizes and last modification times are checked. FULL_OVERWRITE indicates the system always allows overwriting. The system always allows source objects to overwrite their paired destination objects. The value can be: NO_OVERWRITE SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE CRC64_COMPARISON_OVERWRITE FULL_OVERWRITE
dst_storage_policy	String	The destination storage class. This parameter is required only when the destination is Huawei Cloud OBS. The default value is STANDARD. STANDARD: Huawei Cloud OBS Standard storage IA: Huawei Cloud OBS Infrequent Access storage ARCHIVE: Huawei Cloud OBS Archive storage DEEP_ARCHIVE: Huawei Cloud OBS Deep Archive storage SRC_STORAGE_MAPPING: converts the source storage class into an OBS storage class based on the predefined rules. Default value: STANDARD Minimum length: 0 characters Maximum length: 128 characters The value can be: STANDARD IA ARCHIVE DEEP_ARCHIVE SRC_STORAGE_MAPPING
consistency_check	String	The consistency check method, which is used to check whether objects are consistent before and after migration. The selected check method and results will be recorded in the object list. The default value is size_last_modified. size_last_modified is the default setting. The system checks object consistency with object size and last modification time. If a source object is as large as but was last modified earlier than its paired destination object, the system considers the source object has been already migrated successfully. crc64 is only available for migration within Huawei Cloud or from Alibaba Cloud or Tencent Cloud. If a source object and its paired destination object have CRC64 checksums in the metadata, the checksums are checked. Otherwise, their sizes and last modification times are checked. no_check is only available for migration of HTTP/HTTPS data. This option takes effect for source objects whose sizes cannot be obtained from the Content-Length field in the standard HTTP protocol. These source objects are marked as successfully migrated. If the size of a source object can be obtained from the Content-Length field in the standard HTTP protocol, its size and last modification time will be checked. The value can be: size_last_modified crc64 no_check

Status code: 404
