Fast Backups and Restores, Impressive Data Deduplication
Proffer backs up McVean Trading’s data in full backups each day, and he has found that ExaGrid provides quick backup and replication. “With ExaGrid, our backup and offsite replication are completed within the same timeframe of our previous backups, without replication.”
Proffer has been impressed with the data deduplication ExaGrid provides for the different type of data that is backed up on the system. “Our deduplication ratio is nearly 90:1 for our LaserVault data, and we see 50:1 on average for our SQL dumps. ExaGrid’s deduplication allows us to keep more data than we need to. I would need to be stingier by nature if I didn’t have so much storage space available.” He has also been impressed with how quickly data is restored from the ExaGrid system. “Restoring data from ExaGrid is very simple, especially if it’s from a recent backup because that data is already hydrated and waiting. I’ll frequently do test restores in Veeam and they run just like the rest of my virtual infrastructure. It’s hard to tell that it’s a restore from the disk performance,” said Proffer.
ExaGrid writes backups directly to a disk 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 while providing full system resources to the backups for the shortest backup window. Available system cycles are utilized to perform deduplication and offsite replication for an optimal recovery point at the DR site. Once complete, the onsite data is protected and immediately available in its full undeduplicated form for fast restores, VM Instant Recoveries, and tape copies while the offsite data is ready for DR.
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).
