  • Data storage and protection system
    Patent number: 5638509
    Abstract: The data storage and protection apparatus maintains an index of all data file activity on a computer system and stores copies of data files in a manner to enable a user to recreate the state of the computer system at any selected point in time. A data file monitor intercepts all communication between application programs and the file system to obtain data file status and activity information. This information is used to identify data files which are transmitted to a data file backup media for storage along with directory information that identifies the stored files to enable the system to later locate and retrieve data files that were stored on the backup media.
