Bug Description

In some cases, data on the server can become corrupted and has a server_hash of "" reported to the client, which is not retrying the upload. This causes apparent data loss, as the client does not re-upload the correct data, and other clients do not download the corrupt data, which is left on the server and visible in the Web UI.
