You may find yourself with a SpiderOak backup device that is no longer associated with a computer that is available. For example, you may still have a particular device in your account but the physical computer associated with it was disposed of long ago. Best practice is to delete a device that is no longer needed. This will make your account's journals less complicated and improve performance.

You might however need to retain the device, perhaps for compliance reasons or to retain the associated backed up data. In that case, you should update the device to our most recent version for ONE or Groups.
