Managing Fragments

Background Information

Data can be uploaded to OBS using multipart uploads. There will be fragments generated, if a multipart upload fails because of the following causes (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.


OBS Console currently does not support the deletion of all fragments in a batch. You can use OBS Browser+ to delete all fragments at a time. For details, see Managing Fragments.


  1. In the navigation pane of OBS Console, choose Object Storage.
  2. In the bucket list, click the bucket you want to operate to go to the Objects page.
  3. Click Fragments, select the fragment that you want to delete, and click Delete on the right.

    You can also select multiple fragments and click Delete above the fragment list to batch delete them.

  4. Click OK to confirm the deletion.
