Fragments Management


The following lists examples of situations where fragments may be generated due to data upload failures.

  • The network is in poor condition, and the connection to the OBS server is interrupted frequently.
  • The upload task is manually interrupted.
  • The device is faulty.
  • The device is powered off suddenly.

For OBS Browser, if a file fails to be uploaded or the upload task is suspended, fragments are generated and stored in OBS. You can resume the upload through task management. After the resumable upload completes, the fragments will be cleared automatically.

You can also manually clear fragments using the fragment management function. If you resume an upload task after clearing the fragments, the upload progress will be lost and the task needs to be re-uploaded.


The fragment storage in OBS is charged.
