There was a delay with the new version. I'm doing some extensive tests to make sure it really works properly with network support.
I tried a lot of things, from singe file, to random folders, to games with 2000+ files and blu-ray backups of 40GB in size. All seems okay and I'll try to release the new version soon.
Here is an example of what is happening (all tested with 100Mbit network with a cheap router):
Need For Speed SHIFT (a lot of small files)
My Blu-ray copy of Metallica Nimes (France) - almost 40GB
So it seems that will be it... About 30GB per hour.
