ExaGrid Awarded Two Patents

WESTBOROUGH, Mass. -- ExaGrid Systems, Inc.
(, the leader in cost-effective and scalable disk-based backup solutions with byte-level data de-duplication, today announced that the company has patented a method and apparatus for both backing up to a NAS-based system with byte-level delta data de-duplication, as well as ensuring long-term data integrity and recoverability. On file with the U.S. Patent and Trademark Office, the two new patents are: U.S. Patent No. 7,246,140 "Method and Apparatus for Storage System to Provide Distributed Data Storage and Protection"
and U.S. Patent No. 7,246,275 "Method and Apparatus for Managing Data Integrity of Backup and Disaster Recovery Data."

The technology innovation behind these two new ExaGrid patents delivers many real-world benefits for customers, including:

  • NAS-based Disk-based Backup System with Byte-Level Delta Data De-duplication
  • Allows weeks to years of backup history to consume very little
    disk storage capacity and reduce WAN bandwidth requirements
    between the primary site and disaster recovery site
  • Simplifies configuration and management with NAS interface to
    backup applications
  • Enables a cost-effective, scalable architecture that increases
    performance and capacity as backup data continues to grow

    Long-term Data Integrity and Recoverability

  • Maintains the highest levels of backup data integrity over the
    life of the backup data, from weeks to years
  • Eliminates customer concerns of not being able to successfully
    restore files that have been accidentally deleted by users, or recover backup data after a system or site disaster
