The copyObject operation enables copying objects between buckets within the same region, as well as copying objects within the same bucket. Copy operations do not support cross-region copying and require read permissions on the source object. TOS Harmony SDK provides two methods for object copying:

Standard Copy: The size of the copied object must not exceed 5 GiB.

Multipart Copy: Except for the last part, all other parts must be at least 5 MiB in size. The part numbers for uploaded parts must be within the range [1, 10000].
