  • Patent number: 6081875
    Abstract: A backup system and method provides for creation of a reconciled snapshot backup image of a database while the database, residing on a disk array system, is in use by users. A backup computer running a commercial backup utility is connected between the array system and a tape storage system. While the backup is underway, write requests to the database are suspended until the data currently in those data blocks is copied and stored in an original data cache. The disk system address of the copied block and a pointer to the location of the block in the cache are stored in a map. The backup utility incrementally reads portions of the database from the disk system and forwards those portions to the tape system. Prior to each portion being forwarded to the tape system, all data blocks in the portion which have an address that corresponds to the address of a block in the cache are discarded and replaced with the data from the cache for that address.
