DATA DOMAIN

 

Data Domain deduplication storage systems optimize data protection and disaster recovery (DR) performance. Data Domain offers a comprehensive range of products to meet the nearline storage needs of enterprises of all sizes, as they seek to reduce costs and simplify data management. Data Domain systems support all leading enterprise backup and archiving applications for seamless integration into existing IT infrastructures.

 

 



Data Domain systems deduplicate data inline at speeds of up to 1.4TB per hour (22.4TB per hour for the DDX Array).

Data is stored on-site for immediate restores and longer term retention on disk. The deduplicated data can also be

replicated over the WAN to a remote site for disaster recovery purposes, eliminating the need for tape backups, or

for consolidating tape backups to a central location. Data Domain deduplication storage systems provide a dull range

of replication options, including selective replication, many-to-one and bi-directional replication.

Data Domain Global Compression

Data Domain’s Global Compression technology combines an exceptionally efficient, high performance inline deduplication technology with a local compression technique. The deduplication technology reduces data down to its raw essentials by pooling redundant patterns within a file, across files, and even within a block, and stores only unique data segments. Local compression scans the unique data sequence across a local small window of comparison like a tape drive.

Key benefits of Global Compression include:

  • Maximum data reduction, averaging 20x data reduction over time, which minimizes the physical storage capacity required for storing backup images.
  • Extended retention with petabytes (PB) of protection storage, Data Domain systems offer up to 28 PB of useable capacity in a very small footprint.
  • Economy of tape by storing multiple months of backup images for less than $0.35/GB. This extended retention also optimizes performance of both backup and recoveries without making any tradeoffs.
  • Network-efficent replication by transferring only unique data segments, reducing bandwidth requirements by as much as 99%.

Data Invulnerability Architecture

What happens when your data protection storage system fails? Data Domain's Data Invulnerability Architecture lays out the industry’s best defense against data integrity issues, by providing unprecedented levels of data protection, data verification, and self-healing capabilities that are unavailable in conventional disk or tape systems.

Key areas of data integrity protection include:

  • End-to-End Verification at Backup Time
    > Data is read after it is written and verified that it is the correct data and that it is reachable through the file system to disk.
    > Most restores happen within a day or two of backups. Systems that verify/correct data integrity slowly over time will be too late for most recoveries.

  • Fault Avoidance and Containment

    > New data never overwrites good data.
    > Fewer complex data structures.
    > NVRAM for fast, safe restart.
    > No partial stripe writes.

  • Continuous Fault Detection and Healing
    > Data Domain RAID 6 provides double disk failure protection and read error correction.
    > On-the-fly error detection and correction.
    > Scrubbing to find and repair grown defects on the disk before they can become a problem.

  • File System Recoverability
    > Data is written in a self-describing format. If necessary the file system can be recreated by scanning the log and rebuilding it from the metadata stored with the data.

Data Domain Replication Technology

Replication as a data protection technique was once reserved for a very small set of mission-critical application data, certainly not for backup data. Data Domain has changed all that with deduplication storage.

Data Domain replication technology transfers only the deduplicated and compressed unique changes across any IP network requiring a tiny fraction of the bandwidth, time and cost, compared to traditional replication methods.

Data Domain replication technology provides the following benefits:

  • Network-efficient replication for DR provides network-based data protection by securely and automatically replicating backup data to a secure offsite location.
  • Remote office data protection enables network-efficient replication of backup data from multiple branch office to a central hub or data center.
  • Tape consolidation eliminates the need to duplicate backup data at each remote office and leaves tape infrastructure only at a central hub with IT staff.
