ExaGrid Reduced Reliance on Tape, Made Backups Faster
AVH purchased the ExaGrid Tiered Backup Storage system with data deduplication at the recommendation of its parent company’s IT staff. The ExaGrid system works alongside Arcserve Backup to protect the company’s data. AVH replicates data to a stored server and then to the ExaGrid system, which is located in the company’s disaster recovery site. The ExaGrid system is backed up once a week to tape.
“Our parent company highly recommended the ExaGrid system. We like the fact that it is disk-based so we don’t have to fool around with tapes anymore. It saves us a lot of time,” said Sieffers.
“Also, restoring data is a whole lot faster with the ExaGrid because we don’t have to search through tapes. We can do a restore in seconds.” Since installing the ExaGrid system, Sieffers said that nightly backup times have been cut from eight hours to six hours.
“Our backups are now completed each and every night and they’re so much faster,” said Sieffers. “Also, ExaGrid’s data deduplication technology does a fantastic job at compressing our data. I checked our ExaGrid system recently and expected it to be close to full, but we had over 70 percent of our disk space available.”
ExaGrid’s award-winning scale-out architecture provides customers with a consistent backup window regardless of data growth. Its unique disk-cache Landing Zone retains the most recent backup in its full undeduplicated form, enabling the fastest restores, offsite tape copies, and instant recoveries. ExaGrid’s multiple appliance models can be combined into a single system configuration, allowing full backups of up to 2.7PB with a combined ingest rate of 488TB/hr. The appliances virtualize into one another when plugged into a switch so that multiple appliance models can be mixed and matched into a single configuration.
Each appliance includes the appropriate amount of processor, memory, disk, and bandwidth for the data size, so as each appliance is virtualized into the system, performance is maintained, and backup times do not increase as data is added. Once virtualized, they appear as a single pool of long-term capacity. Capacity load balancing of all data across servers is automatic, and multiple systems can be combined for additional capacity.
Even though data is load balanced, deduplication occurs across the systems so that data migration does not cause a loss of effectiveness in deduplication. This combination of capabilities in a turnkey appliance makes the ExaGrid system easy to install, manage, and scale. ExaGrid’s architecture provides lifetime value and investment protection that no other architecture can match.
