**Table 4** Response body parameters
Parameter	Type	Description

count	Long	The total number of synchronization tasks that meet the query criteria. Minimum value: 0 Maximum value: 9223372036854775807

**Table 5** SyncTaskInfo
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. Enumerated values: 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 most recent 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: being synchronizing STOPPED: already stopped Enumerated values: SYNCHRONIZING STOPPED
enable_kms	Boolean	Whether KMS encryption is enabled. This function is disabled by default.
enable_metadata_migration	Boolean	Whether metadata migration is enabled. This function is disabled by default. Even if this function is disabled, the Content-Type metadata will still be migrated to ensure a successful migration.
enable_restore	Boolean	Whether automatic restoration of archived data is enabled. This function is disabled by default. 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
source_cdn	SourceCdnResp object	Whether migration from CDN is enabled. If it is enabled, the source objects to be migrated are obtained from the specified CDN domain name during migration. If this parameter is included, migration from CDN is supported. Otherwise, it is not supported.
object_overwrite_mode	String	How a source object handles its paired destination object, either overwriting the object or skipping the migration. The default value is SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE. NO_OVERWRITE: The system always skips source objects and keeps their paired destination objects. SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE: The system allows overwriting based on the results of size or modification time checks. This is the default value. If a source object has the same name as the paired destination object, the system compares the sizes and last modification time of the source and destination objects to determine whether to overwrite the destination object. The encryption status of the source and destination objects must be the same. If the source object has a different size or was last modified more recently than its paired destination object, the destination object will be overwritten. CRC64_COMPARISON_OVERWRITE: 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 its paired destination object, the destination object will be overwritten. The encryption status of the source and destination objects must be the same. If there are no CRC64 checksums in the metadata, the SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE value is used. FULL_OVERWRITE: The system always allows source objects to overwrite their paired destination objects. Enumerated values: 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: The source storage class is retained and mapped to Huawei Cloud OBS storage class. Default value: STANDARD Minimum length: 0 characters Maximum length: 128 characters Enumerated values: STANDARD IA ARCHIVE DEEP_ARCHIVE SRC_STORAGE_MAPPING
consistency_check	String	The method for checking whether objects are consistent after migration. The encryption status of the source and destination objects must be the same. The check method and results will be recorded in the object list. The default value is size_last_modified. size_last_modified (default): The system checks object consistency with object size and last modification time. If the source and destination objects have the same size and the destination's last modification time is not earlier than the source's, the system considers the source object has been already migrated successfully. crc64: This value is only available for migration within Huawei Cloud or from Alibaba Cloud or Tencent Cloud. After migration, 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: This value 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. In this case, the migration is considered successful once the data is downloaded successfully, without requiring additional data check. 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. Enumerated values: size_last_modified crc64 no_check
