Backup Windows Reduced by 72%, Giving Time for More Backup Jobs
Since installing the ExaGrid system, Green has noticed that backup jobs are much faster. “The ExaGrid sales team made sure to check our environment to give us the right network card and appliance size, and since we now use 10GbE network cards, our network throughput has tripled,” he said. “The ingest speed has been amazing, averaging at 475MB/s, now that the data is written directly to ExaGrid’s Landing Zone. Our backup window used to be 11 hours for our daily backups, and now those same backups finish within 3 hours.”
Green used to back up the school district’s data on a daily basis but has been able to add synthetic fulls to the regular backup schedule, increasing the data available for restoration. “With our previous solution, we were barely able just to get our dailies in, and never have had time to make synthetic fulls for the week or the month. Now, our daily backup jobs are finished by midnight, which leaves Veeam open to do things like biweekly synthetic backups, so I feel we are better protected with multiple restore points that I can go back to in case any data gets corrupted. I could probably add more fulls without any issue.”
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).
ExaGrid has integrated the Veeam Data Mover so that backups are written Veeam-to-Veeam versus Veeamto- CIFS, which provides a 30% increase in backup performance. Since the Veeam Data Mover is not an open standard, it is far more secure than using CIFS and other open market protocols. In addition, because ExaGrid has integrated the Veeam Data Mover, Veeam synthetic fulls can be created six times faster than any other solution. ExaGrid stores the most recent Veeam backups in an undeduplicated form in its Landing Zone and has the Veeam Data Mover running on each ExaGrid appliance and has a processor in each appliance in a scale-out architecture. This combination of Landing Zone, Veeam Data Mover, and scale-out compute provides the fastest Veeam synthetic fulls versus any other solution on the market.
