  • Systems and methods for enabling deduplication of attachment files within a database
    Patent number: 9244936
    Abstract: A computer-implemented method for enabling deduplication of attachment files within a database is described. A database file comprising data blocks of an attachment file positioned intermittently among data blocks of the database file is inspected. A first map may be generated from the inspection of the database file and the attachment file. The data blocks of the database file and the data blocks of the attachment file are identified according to the first map. The data blocks of the database file are written to a database data file. The data blocks of the attachment file are written to an attachment data file. The attachment data file is deduplicated with at least one other data file.
