Works the way a USB stick should work. Creates a USB backup drive to boot from USB and works great with Acronis backups. I found it a bit pricey but I've bought USB sticks that didn't work with Acronis and I don't think Acronis is to blame. Other USB flash drives either didn't create a boot drive, or if they said so, they didn't boot at all. So maybe it was worth paying a little more.
