The copyObject operation enables copying objects either between buckets within the same region or within the same bucket. Copy does not support cross-region copying and requires read permission on the source object.

Copy Object Description

The TOS Browser SDK provides the following object copy methods:

Standard Copy: The size of the object to be copied 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].

Resumable Copy: Applicable to scenarios where large objects are copied within a single bucket or between two buckets in the same region using the SDK.
