EMC Data Domain

                 Data Domain Corporation was an Information Technology company from 2001-2009 specializing in target-based deduplication solutions for disk based backup.[1] Since its acquisition by EMC Corporation in 2009, Data Domain was founded by Kai Li, Ben Zhu, and Brian Biles.[2] Chief Architect Hugo Patterson joined 3 months after initial funding. The first product revenue was in the beginning of 2004.

                 In June 2009, EMC Corporation announced their intention to acquire Data Domain Corp for $2.4B, outbidding NetApp's previous offer.[5] In July, the two companies reached definitive agreement regarding the acquisition. Since then, Data Domain systems have been a product line brand within the EMC Core Technologies portfolio. According to IDC, EMC in 2014 captured 62.3% share of the market for purpose-built backup devices worldwide. The majority of this share was from Data Domain product revenue.

Domain systems have since significantly surpassed this capacity and speed:

High-Speed Deduplication
The EMC Data Domain Operating System delivers industry-leading speed and efficiency through variable-length deduplication. With performance up to 58.7 terabytes per hour, organizations can meet the most challenging backup windows while reducing backup and archive storage requirements by 10 to 30 times, making disk a cost-effective alternative to tape.
Seamless Integration
DD OS enables EMC Data Domain systems to integrate seamlessly with existing infrastructures including leading backup, archive, and enterprise applications. A Data Domain system can protect the entire enterprise including backup for Oracle, Microsoft, VMware, IBM i, open systems, big data and mainframe environments as well as file and email, database, enterprise content management, and virtual machine archiving.
Network-Efficient Replication
With the DD OS, organizations can replicate backup and archive data off-site faster, with minimal bandwidth for safe, tape-free disaster recovery. Data Domain systems provide flexible replication topologies to optimize your backups such as full-system mirroring, selective, bidirectional, many-to-one, one-to-many, and cascaded.
Reliability and Security
The Data Domain Data Invulnerability Architecture is core to DD OS and is built into every system, providing the industry’s best defense against data integrity issues. Inline write-and-read verification, continuous fault detection, and self-healing ensure that backup and archive data is accurately stored, retained, and recoverable or accessible throughout its lifecycle on a Data Domain system. Combined with the ability to meet compliance regulations and security requirements, no other storage system provides this level of protection.
Cloud Readiness
DD OS provides secure multitenancy, which delivers data isolation for enterprises and service providers looking to deploy Data Domain systems in a private or public cloud. With secure multitenancy, a Data Domain system logically isolates tenant data, ensuring that each tenant’s data is only visible and accessible to them. Multitenant management and monitoring enables chargeback, trending, and tenant-level reporting.

Why Data Domain:

       Less disk to resource, less to manage
      CPU-centric deduplication

       Simple, mature, and flexible
      Simple, mature appliance
      Nearline tier: any fabric, any software, backup or nearline applications

       Resilience and disaster recovery
      Storage of last resort
      Cross-site global compression: data center or remote office
