RudiC, I don't think he's trying to parallelize the upload, just send the first tenth without waiting for the computer to finish processing the last tenth.
Step back a little. Why are you using rsync to send 10 files? What exact problem is being solved by splitting and transferring the file this way? Is your connection unreliable?
I don't think you can "trick" rsync into using incomplete files, you may need to arrange something else. It may be possible to avoid splitting the file at all!
What kind of connection do you have between yourself and the destination? 2 tb in 2 days sounds pretty fast. Are you on the same subnet, even virtually?
What's your operating system? On Linux, I think you can use losetup to create a device that's a "view" into a file on disk. So instead of creating a 200 gigabyte file, you'd just create a device which maps to the first 200 gigabytes with no copying or fuss. Whether rsync will swallow loopback files remains to be seen.
If you don't need to use rsync to transfer, you can just grab sections of file by any means you like and transfer them without writing the split file to disk at all.
