[ABR11] second location problem.

Hello,

I'm currently testing ABR 11 (release 17217)

I use a laptop / win7 FR / fresh install

backup location n°1: network share on a Qnap nas server
backup location n°2 : USB drive connected on the laptop.

I created a job, with a "main" location and a 2nde copy.

First task succeeded without any problem.
Then, the second task.

In fact, the copy task from network share to USB drive begins and stops suddenly after 80 Mb....

Any idea ?
