Creating a Migration Task

Function

This API is used to create a migration task. After the migration task is created, it will be automatically started.

Constraints

  • A tenant can create a maximum of 1,500 migration tasks within 24 hours.

  • A tenant cannot create more migration tasks if the tenant already has 1,500 migration tasks in the Waiting to migrate state.

Calling Method

migrate_since

No

Long

A timestamp in second. The system migrates only the objects that are modified after the specified time. No time is specified by default.

Minimum value: 0

Maximum value: 9223372036854775807

Default value: 0

bandwidth_policy

No

Array of BandwidthPolicyDto objects

The traffic limiting rules. Each element in the array corresponds to the maximum bandwidth in a time period. A maximum of five periods are allowed, and the periods cannot overlap.

Array length: 0 to 5

source_cdn

No

SourceCdnReq object

Indicates whether migration from CDN is enabled. If this field is contained, migration from CDN is supported. Otherwise, it is not supported. If migration from CDN is enabled, the source objects to be migrated are obtained from the specified CDN domain name during migration.

smn_config

No

SmnConfig object

The SMN message sending configuration.

enable_metadata_migration

No

Boolean

Indicates whether metadata migration is enabled. The default value is false. Even if this function is disabled, the ContentType metadata will still migrated to ensure a successful migration.

Default value: false

enable_restore

No

Boolean

Indicates whether archive data restoration is enabled.

If this function is enabled, archive data is automatically restored and migrated.

Default value: false

enable_failed_object_recording

No

Boolean

Indicates whether to record failed objects. This function is enabled by default.

If this function is enabled, information about objects that fail to be migrated will be stored in the destination bucket.

Default value: true

object_overwrite_mode

No

String

Indicates whether to skip a source object or allow the source object to overwrite its paired destination object. The default value is SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE. NO_OVERWRITE: indicates the system never allows overwrite. The system always skips source objects and keeps their paired destination objects. SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE: indicates the system allows overwrite 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 overwrite if the source and destination objects have different CRC64 checksums. This option is only available for migration on 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 one of them does not have a CRC64 checksum, their sizes and last modification times are checked. FULL_OVERWRITE: indicates the system always allows overwrite. The system always allows source objects to overwrite their paired destination objects.

Value options are as follows:

  • NO_OVERWRITE

  • SIZE_LAST_MODIFIED_COMPARISON_OVERWRITE

  • CRC64_COMPARISON_OVERWRITE

  • FULL_OVERWRITE

Maximum length: 128 characters

The value can be:

  • STANDARD

  • IA

  • ARCHIVE

  • DEEP_ARCHIVE

  • SRC_STORAGE_MAPPING

consistency_check

No

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: It 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 does not need to be migrated or has been already migrated successfully. crc64: This option is only available for migration on Huawei Cloud or from Alibaba Cloud or Tencent Cloud. If a source object and its paired destination object have CRC64 checksums, the checksums are checked. Otherwise, their sizes and last modification times are checked. no_check: This option is only available for migration of HTTP/HTTPS data. This option takes effect for source objects whose sizes cannot be obtained using the content-length field in the standard HTTP protocol. These source objects will overwrite their paired destination objects directly. If the size of a source object can be obtained, its size and last modification time will be checked.

Default value: size_last_modified

Value options are as follows:

  • size_last_modified

  • crc64

  • no_check
