Abstract
A method of safeguarding against loss of data stored in a portable data storage device or loss of the data storage device itself is described. A user-carried backup device having memory and a wireless communication link for communicating with the portable data storage device is provided. The backup device and the portable data storage device communicate periodically or quasi-continuously over the wireless communication link and may backup data entered into the portable data storage device and check for removal of the portable data storage device. An alarm is activated to alert a user to loss of the portable data storage device if the portable data storage device is out of range of communication for a predetermined period.
