One main advantage of increasing computer capabilities is that multiple software application functions can be incorporated onto a small piece of hardware. However, software crashes, misuse and power glitches often cause computer down time. The complexity of today's software demands considerable recovery time for reinstallation and reconfiguration.

Dependence on computers makes timing critical, and computer failures have a tremendously negative impact on productivity. Waiting hours and days for service engineers to bring computers back to working condition is simply no longer an option.

Computer maintenance in hardware labs is a constant struggle as computers are often disabled minutes after being repaired. Down time of business computers is a direct cause of heavy company losses, and the IT (Information Technology) industry can no longer afford down time in "mission critical" services.

Today's existing backup and recovery solutions do not efficiently prevent computer down time. Procedures such as image cloning, policy restrictions and "undo solutions" require complex configuration and operation, place limitations on user flexibility by blocking access to files and directories, and consume vast amounts of resources (handling time, HDD space, RAM and computer performance).
