Data deduplication with Data Domain

Data Domain helps control storage costs with the highest data reduction ratio in the industry

Data Domain has become a market leader in de-duplication technology. Its unique data deduplication technology provides maximized data reduction, averaging a 20X reduction in capacity requirements.

• provides reliability and high availability with continuous verification of data & fault monitoring, and automatic healing capabilities
• seamlessly integrates with existing backup applications & storage fabrics
• increased data reduction because of unique de-duplication to the variable segment level, not file- or block-level
• handles multi-site replication easily
• brings the cost of DR within reach for SMBs

Global Compression

Data Domain’s unique compression algorithm enables efficient inline data deduplication in a way that maximizes the reduction of data. Their de-duplication technology finds redundant patterns across files, within file, and even across blocks of data. As an example, a presentation being emailed within a team while everyone makes small changes can bloat capacity in systems that deduplicate at the file level, while Data Domain will de-duplicate the common slides, reducing the backup server load, storage capacity requirements, and WAN costs if data is backed up remotely.

Enhanced Data Protection

Data Domain’s deduplication software verifies data end-to-end, throughout the backup cycle. Especially useful for D2D backup situations, data is inspected on-the-fly, self-corrected, & healed as necessary to ensure data integrity. RAID6 capability protects against dual drive failures, and NVRAM allows for quick and safe restarts.

Recoverability and the ability to restore is maximized with Data Domain de-duplication technology. By performing inline detection and correction of errors and constant recovery verification, you can be rest assured that all of your backups are safe with a system that catches problems instantly instead of days later. Data Domain’s unique data duplication software can even recreate entire filesystems if necessary.

Replication Technology

Data Domain helps alleviate some of the costs involved with backing up and remotely replicating data for disaster recovery & WAN vaulting. Its replication software employs delta differencing to copy only unique blocks of data, further lower bandwidth costs associated with DR & offsite archival.

Inline de-duplication v.s. offline de-duplication

There are two main methods of implementing deduplication: inline or offline. Inline de-duplication is performed at the host application, or on an appliance sitting on the data path, which minimizes disk capacity requirements, thereby maximizing cost-savings achieved by reduced disk requirements.

Data Domain employs inline deduplication solutions, which helps to minimize bandwidth requires for remote replication, vaulting and disaster recovery.
