Something is still broken, while testing with your patches applied I am not able to edit an existing PBS storage backend.

When I try to e.g. disable the storage via the WebUI I get the following error:
`update storage failed: PBS-local: Cannot find datastore '', check permissions and existence! (500)`
Without your patches applied everything works as expected again.

Cheers,
