ExaGrid Reduces Backup Times, Provides Data Deduplication to Maximize Storage Efficiency
After briefly considering backing up to straight disk, the College chose ExaGrid. The ExaGrid system works with the College’s existing backup application, Arcserve.
“We easily could have built something ourselves with massive disks, but we wouldn’t have had the data deduplication necessary to reduce our data. Also, the power draw and footprint alone for a system like that wouldn’t have been practical in a co-location facility, where we pay for rack space and are subject to electrical surcharges,” said Jameson.
Since moving its backups to ExaGrid, the College’s weekly full backups have been reduced from 24 to 36 hours to 10 to 12 hours. Nightly differential backups have been reduced from six hours to less than two hours. One of the main reasons the College chose ExaGrid was its built-in data deduplication technology.
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’s data deduplication technology enables us to maximize the amount of data we can back up onto the system,” said Associate Director, Information Technology Khanh Tran. “Overall, we’re trying to reduce our energy usage and the ability to backup massive amounts of data onto ExaGrid’s 3U footprint certainly helps.”
