ExaGrid’s Adaptive Deduplication Process Eases Replication
The General Court installed an ExaGrid system at its primary site that replicates data to a second ExaGrid system for disaster recovery (DR). Larose has found that the ExaGrid-Veeam solution easily backs up the virtualized environment. Larose backs up the General Court’s data on a daily basis, in addition to a weekly and monthly backup and is pleased with how time-efficient backups are. “Our backups take about 40 minutes,” he said.
“The ExaGrid system is so reliable. We haven’t had any issues, it’s very much a set-it-and-forget-it solution.” He especially appreciates ExaGrid’s Adaptive Deduplication process, which has eased strain on the network. “One of the best features about ExaGrid is that it deduplicates our data before it’s replicated to our DR site. Now that there is less data moving over to the second site, we’ve noticed an improvement from before, when full, undeduplicated data was streaming across the fiber connection,” said Larose.
ExaGrid writes backups directly to a disk-cache Landing Zone, avoiding inline processing and ensuring the highest possible backup performance, which results in the shortest backup window. Adaptive Deduplication performs deduplication and replication in parallel with backups for a strong recovery point (RPO). As data is being deduplicated to the repository, it can also be replicated to a second ExaGrid site or the public cloud for disaster recovery (DR).
“Using ExaGrid has given me a sense of security, since I know our backups are available and can spin up fast. I can tell the COO with confidence that if anything ever goes down, we have the resources to restore our data and we will be able to get up and running again quickly.”
ExaGrid and Veeam can instantly recover a file or VMware virtual machine by running it directly from the ExaGrid appliance in the event that the file is lost, corrupted or encrypted or the primary storage VM becomes unavailable. This instant recovery is possible because of ExaGrid’s Landing Zone – a high-speed disk cache on the ExaGrid appliance that retains the most recent backups in their complete form. Once the primary storage environment has been brought back to a working state, the VM backed up on the ExaGrid appliance can then be migrated to primary storage for continued operation.
