Data Domain Extended Retention Long-term retention of backup data
EMC Data Domain Extended Retention provides an internal tiering approach that enables cost-effective, long-term retention of backup data on an EMC Data Domain system. With it, customers can leverage Data Domain systems for long-term backup retention and minimize reliance on tape.
Data Domain Extended Retention transparently incorporates two tiers of storage on a Data Domain system to achieve cost-effective scalability while delivering the throughput required to ingest hundreds of terabytes of backup data. This combination makes Data Domain systems the ideal tape elimination solution for long-term backup retention.
Data Domain Extended Retention provides transparent separation of short-term and long-term backup data by storing it in different tiers on Data Domain systems. Data is initially stored in the active tier for backup and operational recovery, then moved to an extremely scalable retention tier that’s optimized for long-term data retention—usually measured in years.
It ensures long-term data access and recoverability with fault isolation so that in the event of a failure or catastrophe the system continues to operate with all unaffected components.
Data Domain Extended Retention enables granular unit-to-unit replication for disaster recovery. In the event of a connectivity issue affecting the replication process, the Data Domain system only needs to replicate the impacted unit to resynchronize.
Gain fast, secure backup and recovery for your VMware environments, remote offices, desktops, laptops, and data center with client-side deduplication.
