I use True Image 11 (newest build) on Windows Vista (all available updates installed) on a Thinkpad X61t (Core2 duo, 2 GB RAM) and want to backup my data folders to a USB harddisk. Somewhere in the middle of the process it stalls forever, without any more progress, CPU utilization drops to zero and I cannot cancel the backup other than ending the tasks manually in task manager. I have tried it several times including trials with no other programs running (not even anti-virus, etc.). The result is always the same, I have never managed to complete a backup. What can be done about the situation?
