How does OSS handle file uploads during interruptions?

When using Alibaba Cloud Object Storage Service (OSS) for file uploads, if an interruption occurs during the upload process, the service effectively retains the parts of the file that have already been successfully uploaded. This means that, in the event of an upload failure or interruption—perhaps due to network issues or system errors—any data that was previously uploaded is not lost and can still be used to complete the upload of the entire file.

This capability is particularly important for large files, as it saves time and bandwidth that would otherwise be wasted in re-uploading the entire file after an interruption. Users can resume the upload process from the point at which it stopped by utilizing the parts that have already been stored, leading to a more efficient and reliable upload experience.

In contrast, the other options imply a less effective handling of file uploads, which does not align with OSS’s behavior of preserving successfully uploaded parts in the event of interruptions.
