  • Central computer backup system utilizing localized data bases
    Patent number: 4710870
    Abstract: A distributed information backup system is disclosed. The inventive backup system includes a first computer which accesses data from a central data base and periodically distributes the data to a predetermined multiplicity of other computers upon request therefrom. Each of the other computers receives only a portion of the distributed data and thereupon updates a local data base with the data each receives. When the central data base is inaccessible, a data base user accesses one of the local data bases through one of the multiplicity of computers to obtain the data which it would ordinarily obtain from the central data base to perform his tasks.
