EMC enhances disaster recovery credentials
Cascaded replication is bolted-on to Data Domain’s inline deduplication solutions as one of the first major developments from EMC since it brought out the company recently
EMC has added cascaded replication capabilities to the line-up of deduplication storage solutions that it now owns after the recent acquisition of Data Domain. The move will enable enterprise organisations to boost their disaster recovery strategies by electronically transferring back-up and archive data to an off-site location.
The vendor claims that the cascaded replication is a first for the industry and is one of several enhancements that it has carried out to the Data Domain Replicator software in an effort to provide scalable, enterprise-ready deployment flexibility to large, distributed enterprises.
“Most deduplication storage systems are very immature and inflexible in replication,” asserted Brian Biles, vice president of product management of EMC’s Backup and Recovery Systems Division and the co-founder of Data Domain in 2001.
“Data Domain Replicator not only has more production implementations and years of production use than comparable deduplicating VTLs, it also has significant functionality differentiation, as demonstrated by these new features,” he added.
The company explains that most Data Domain systems include its Replicator software, which enables the rapid transfer of data over low-bandwidth WAN links to accelerate disaster recovery readiness and reduce WAN costs.
The Replicator now supports software 180-to-1 remote site fan-in to a single controller for expanded automated cross-site deduplication and up to 100% faster directory replication throughput using optimised, multi-stream replication.
End-users can achieve faster times to disaster recovery thanks to a combination of high speed inline deduplication, cross-site deduplication and simultaneous vaulting of data offsite. In addition to that it is possible to extend protection to additional offsite locations, adding further resilience to data sets where a single disaster recovery site is not sufficient.
