Managing Fragments

Background Information

Data can be uploaded to OBS using multipart uploads. Fragments are generated, if a multipart upload fails because of the following reasons (included but not limited to):

  • The network is in poor conditions, and the connection to the OBS server is interrupted frequently.

  • The upload task is manually suspended.

  • The device is faulty.

  • The device is powered off suddenly.

On OBS Console, storage used by fragments is charged. Clear fragments when they are not needed. If a file upload task fails, upload the file again.


Generated fragments take up storage space that is billable.
