Summary: I bought ATI2011 for its Non-Stop Backup feature. It turns out the software is not smart enough to deal with external hard drives. "Oh well", I thought, and created an hourly backup. At first, I went with the incremental backup, but when I had to restore a few files, it served an half-baked copy of my backups, so I've tried the standard backup, and it worked ok. Later, I've tried to move it to a networked drive, and suprise surprise! it crashed the program.
