With copyObject, you can copy objects between buckets in the same region, or within the same bucket. Copying does not support cross-region transfers and requires read access to the original object. The TOS Node.js SDK provides three methods for copying objects:

Standard Copy (Node.js SDK):The size of the object does not exceed 5 GiB.

Multipart Copy (Node.js SDK): Except for the last part, other parts need to be greater than or equal to 5 MiB in size, and the number range of uploaded parts is [1,10000].

Resumable Copy (Node.js SDK): Suitable for scenarios where large objects are copied within a single bucket or between two buckets in the same region through the SDK.
