Data Deduplication Maximizes Storage Capacity
The backup environment at the Museum is about 95% virtual, with only a couple of physical targets. “ExaGrid works very well with both scenarios. We’ve sorted our data from most critical to less critical, and back up our more important and often-changed servers daily and keep copies of them for a longer retention and our less critical servers are backed up once a week and have a shorter retention,” said Dahlin.
“With the combination of Veeam and ExaGrid, we are seeing very strong deduplication and having everything consolidated is making a huge positive impact on performance,” he said. Veeam uses changed block tracking to perform a level of data deduplication. ExaGrid allows Veeam deduplication and Veeam dedupe-friendly compression to stay on. ExaGrid will increase Veeam’s deduplication by a factor of about 7:1 to a total combined deduplication ratio of 14:1, reducing the storage required and saving on storage costs up front and over time.
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).
