Abstract

An information backup system comprises a first computing system including a first local disk that includes a first disk driver. The first computing system also includes first local RAM, a first network interface that is connected to a computer network and includes a first network driver. A first device driver/bridge responsive to communications from the first network driver and the first disk drive writes data to and reads data from the first local RAM. A second computing system also includes second local RAM and a second network interface that is connected to the computer network and includes a second network driver. A second device driver/bridge responsive to communications from the second network driver and the second disk driver writes data to and reads data from the second local RAM.

Claims

1. An information backup system, comprising:

A. a first computing system including

(i) a first local disk that includes a first disk driver;

(ii) first local RAM;

(iii) a first network interface that is connected to a computer network and includes a first network driver;

(iv) first means responsive to communications from said first network driver and said first disk driver, for writing data to and reading data from said first local RAM;

B. a second computing system including

(i) a second local disk that includes a second disk driver;

(ii) second local RAM;

(iii) a second network interface that is connected to the computer network and includes a second network driver; and

(iv) second means responsive to communications from said second network driver and said second disk driver, for writing data to and reading data from said second local RAM.

2. The information backup system of claim 1, wherein said first means for writing data communicates with said first disk driver to cache data in the first local RAM.
