Hum... At first moment, I thought I/O could being a trouble, since I was ran backup in USB devices. But now, I ran backup task on SAS disk! So performance and I/O is not an issue here... And, I can't shrink the file, because the entire disk is being used to all databases as I described before...
If somebody else has any other advice, I will appreciate...
