  • Reducing bitmap management overhead
    Patent number: 7506112

The contents of the shadow copy are examined as are the bitmap cache to determine when it is necessary to write bitmap data to persistent storage. Extra bits are set or left set in the bitmap shadow copy to minimize the frequency of having to write bitmap data to persistent storage.
