Snapshot file:media at 0% abort

When I try to make backup using snapshot pro, everything goes smooth until it reaches the "File".

It stops there, the progress bar stays at 0% the whole time, then after some time it gives me an error like it was trying to use the "Search" and found nothing, and the only option left is to abort there.

So my question is, the rest of the backup was saved, just the media was left out?
If that's the case, how do I backup the media?
