With Data Domain OpenStorage software, administrators can control replication between multiple Data Domain systems from the NetBackup console. This paradigm is designed to be very familiar to NetBackup users such that replication of data over the WAN using Data Domain Replicator Software feels similar to vaulting a copy of the data to tape. All copies of the backup images are present and consistent in the NBU catalog which allows a single management console view to be available to the administrator.
Data Domain leverages its WAN efficient replication technology to vault the images from one system to another system directly, when both systems are configured with Data Domain OpenStorage software. Using this optimized replication approach — which can reduce the bandwidth required for replication by 99% — users can dramatically reduce the time needed to create duplicate copies of their backups for consolidation or disaster recovery purposes.
Resource usage on the media server is also reduced as it is no longer in the data path when duplicate copies of the backup are being created. This makes it very easy and cost efficient to recover data at remote sites. Since tape is no longer required at these sites, it is entirely practical to deploy Data Domain systems with Data Domain OpenStorage software as the key, foundational elements of a multi-site tape consolidation strategy.
