TOS SDK can copy objects between buckets within the same region or within the same bucket. Copying does not support cross-region transfers and requires read permission on the source object.

TOS SDK offers three methods for object copy:

Standard Copy: Copies objects up to 5 GiB in size.

Multipart Copy: Except for the last part, each part must be at least 5 MiB; part numbers range from 1 to 10,000.

Resumable Copy: Suitable for copying large objects within a single bucket or between two buckets in the same region via the SDK.
