  • Methods and systems for protecting data from potential corruption by a crashed computer program
    Patent number: 6631480
    Abstract: The present invention is directed toward creating backup copies of previously saved data before it is modified by a crashed computer program executing in a preemptive multitasking operating system environment. The invention is advantageous in that it protects against data loss and corruption caused by operating system calls issued by malfunctioning, crashed computer programs. A method in accordance with the invention comprises the steps of: (a) monitoring operating system calls made by a crashed program; (b) intercepting a selected group of operating system calls made by a crashed program before they are executed by an operating system; (c) logging a subset of the selected group of intercepted operating system calls in a memory; (d) creating backup copies of data potentially modified by a further subset of the selected group of intercepted operating system calls; and (e) passing intercepted operating system calls to an operating system.
