| Global deduplication is a method of preventing redundant data when backing up data to multiple deduplication devices. This method may involve backing up to more than one target deduplication appliance or, in the case of source deduplication, backing up data on multiple clients. With global deduplication, when data is sent from one node to another, the second node recognizes that the first node already has a copy of the data and does not make an additional copy. This is more efficient than single-node deduplication, which only deduplicates data sets residing on that node. Because large data centers use multiple backup targets, global deduplication is the preferred deduplication technology because it removes all the redundant copies of data across all targets. In an organization with a high volume of data, other forms of deduplication could result in a bottleneck. Today, all major data backup software applications and targets with dedupe capabilities offer global deduplication. Vendors include Arcserve, Asigra, Carbonite, Cohesity, Commvault, Dell EMC, Druva, ExaGrid, HybriStor, Rubrik, Veeam Software and Veritas. Read more.... |
