Proxure, a developer of information backup and synchronisation technologies, has expanded its KeepVault online backup offerings with the introduction of a new software offering called KeepVault Key targeted toward manufacturers of USB, SD, xD, CompactFlash and memory stick-type flash memory cards.

The company said that the KeepVault Key when pre installed on any of the above devices, will automatically backup the device’s content to an online storage account when the device is connected to a PC. It can be configured to sync selected files from the USB keychain or flash memory card to the PC or online services such as Facebook and Flickr.

According to Proxure, the 128-bit AES encrypted KeepVault Key allows users to back up multiple computers to a single online storage account, and provides centralised online storage and sync options.

The KeepVault online storage accounts range in size from 40GB to several Terabytes. In addition, it provides recurring revenue-sharing opportunities for memory device manufacturers that deploy the application on their memory devices, the company claims.
