The patent (for a "System for automatically recovering a computer memory using shadowed data and file directory structures") is directly related to the Rebit technology for storing data in a novel way. The result enables a point-in-time restore of the computer system disk drive. Each full image of a system hard drive is a heavy operation and consumes the computer resources during that operation. Typically, this operation would be performed on a regular basis, say weekly or monthly. The Rebit technology allows for an initial backup and then a light-duty operation each day to obtain the same results as a full image, thus reducing the toll on system resources.
In addition, each file is tracked and backed up such that multiple copies of the same file are available to the user through Rebit restore, whether simply a file restore or an entire system drive restore. In essence, even though Rebit is the easiest and simplest backup technology to use, it is both intelligent and complex under the hood.
