Failed to copy from Source when using Box

I'm testing the new "Cloud" backup options, so far mainly Box and Google Drive.

Backups seem to run first time, but I get errors on Box if the a file was changed and it exists on the destination.

Big long errors messages in the log - e.g.

Failed to copy from Source : HTTP/1.1 409 Conflict<br><br><tt>Recv 30/10/2014 1:09:04 AM: HTTP/1.1 200 OK<br>Server: nginx<br>Date: Thu, 30 Oct 2014 05:09:45 GMT<br>Content-Type: application/json<br>Content-Length: 1144<br>Connection: keep-alive<br>Cache-Control: no-cache, no-store<br><br>{"total_count":4,"entries":[{"type":"folder","id":"2625596555","etag":"0","size":1354036,"name":"AAA","parent":{"type":"folder","id":"0","sequence_id":null,"etag":null,"name":"All Files"},"modified_at":"2014-10-29T15:01:19-07:00","content_modified_at":"2014-10-29T15:01:19-07:00"},{"type":"folder",<br>Sent 30/10/2014 1:09:04 AM: GET /2.0/folders/2623514569/items?limit=1000&offset=0&fields=size,id,etag,sha1,name,parent,type,modified_at,content_modified_at HTTP/1.1<br>Content-Type: application/x-www-form- ........ etc.

Testing the same data on Google drive - it works and create a correct version sub-directory.

Also on Box - it gets annoying when it keeps asking for permission from Box and having to enter a password/key.
