Backup Device - Clickfree Traveler

The gadget has the size of a credit card and has a very small weight (16Gb = 30g). Clickfree Traveler connects to a computer through a USB port, scans hard drives, and then saves in its memory all the necessary information, structured by file type, supports more than 400 different file types. Clickfree Traveler creates an incremental archive, and every time thereafter, there will be a backup of the files that have been changed.

It is a miracle.
Clickfree ™ Traveler - FL160. Price: US $ 79.99 (at 16Gb)
There are also 32 and 64 Gb. In my opinion to back up important information of this volume is quite enough.
