EMC Data Domain Extended Retention Software

January 4, 2020


Hi – I’m Caitlin Gordon from the EMC Backup
Recovery Systems Division. I’m here today to talk to you about the Data Domain Extended
Retention software option, which provides long-term retention of backup data on Data
Domain systems. Today’s we’ll discuss how DD Extended
Retention provides cost-optimized scalability, fault isolation as well as granular replication. EMC Data Domain Extended Retention software
provides internal tiering approach that enables cost-effective, long-term retention of backup
data on a Data Domain system. Using DD Extended Retention Software, customers can leverage
Data Domain systems for long-term backup retention and minimize reliance on tape. DD Extended
Retention software 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 reduction solution for long-term backup retention. DD Extended Retention software provides a
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 it is moved to a very large retention tier that is optimized for long-term
data retention—usually measured in years. DD Extended Retention ensures long-term data
access and recoverability with fault isolation. Specifically, the retention tier, which consists
of multiple retention units, will seal each retention unit when it reaches full capacity.
When it is sealed, it becomes a self-contained unit to ensure long-term data preservation.
As a result, even if a failure or a catastrophe affects major components of a Data Domain
system, the system continues to operate with all unaffected components. DD Extended Retention also 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. In addition, if a disaster impacts the availability of the primary retention
unit, only the affected unit has to be recovered. To summarize, DD Extended Retention provides
cost-optimized scalability, fault isolation as well as granular replication. For more information about Data Domain systems,
