50% Faster Backups and Quick Restores
Esopenko backs up Ogilvie’s data on a daily, weekly, and monthly basis to the ExaGrid system, using Veeam. Since switching to ExaGrid, he has added backups on Saturday and Sunday, and has been impressed that adding backups has not caused a strain on storage capacity. “Our backups take half the time now, from 16 hours with Data Domain to eight hours using ExaGrid, and it’s been nice to close the backup window a bit. Restoring files is a quick process, too, especially because data doesn’t need to be rehydrated when it’s restored from ExaGrid’s Landing Zone,” said Esopenko.
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). Veeam uses the information from VMware and Hyper-V and provides deduplication on a “per-job” basis, finding the matching areas of all the virtual disks within a backup job and using metadata to reduce the overall footprint of the backup data. Veeam also has a “dedupe friendly” compression setting which further reduces the size of the Veeam backups in a way that allows the ExaGrid system to achieve further deduplication. The net result is a combined Veeam and ExaGrid deduplication rate of 6:1 upwards to 10:1, which greatly reduces the amount of disk storage required.
