New description:

 I have found an issue with uploading large data sets to GreenQloud (S3
 compatible) and found a way to repeat the problem.

 I have a hard drive that I wanted to upload to GreenQloud's StorageQloud.
 The root of the hard drive has about 10 folders and within those folders
 are more nested folders (with utf-8 names and deep nesting) and thousands
 of images, video files etc. roughly 300GB. If I select all of them and
 drag to upload in CyberDuck then the app will prepare for a very long time
 and then chug along and even get better and better upload speeds. However
 when I checked the folders on the remote service - all or most files are 0
 bytes. CyberDuck silently failed to upload the contents for each object
 and even reported that it had transfered all of the data (in terms of
 transmitted data).

 At first I thought this must be GreenQloud's service failing but after
 watching the GQ logs and finding nothing suspicious there I did a lot of
 testing within CyberDuck. I realised that individually uploading each root
 folder worked perfectly with no 0 bytes files. There could possibly be
 something failing in the staging/preparing phase in Cyberduck. I did see
 some string to date errors in the Console.app but I'm not sure if that was
 related to the issue.

 cheers
 Eiki, CEO GreenQloud
