This API uploads a part by copying data from an existing object as the data source. Each part must be at least 5 MB in size, except for the last part. The maximum size of each part is 5 GB. Table 24 shows the details about the OneFS S3 UploadPartCopy API request parameters and request body. If not specified, OneFS silently ignores all unsupported request parameters and the request body, without returning an error code to the client.
