Deduplication Reduces Data Stored, Scale-out Architecture Provides Easy Scalability
Fuller said that the company’s data growth had been constant, but due to a spike in new cases recently, the IT staff has seen a dramatic increase in the amount of backup data they now handle. Keeping pace with data growth has been more manageable with ExaGrid’s built-in data deduplication technology, and its scale-out architecture will ensure that the system serves the company for years to come. “ExaGrid’s data deduplication technology reduces our stored data by 14:1, and it’s great that we have
the ability to easily upgrade the system to handle increased capacity,” said Fuller.
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 appliance models can be mixed and matched into a single scale-out system allowing a full backup of up to 2.7PB with a combined ingest rate of 488TB/hr, in a single system. The appliances automatically join the scale-out system. Each appliance includes the appropriate amount of processor, memory, disk, and bandwidth for the data size. By adding compute with capacity, the backup window remains fixed in length as the data grows. Automatic load balancing across all repositories allows for full utilization of all appliances. Data is deduplicated into an offline repository, and additionally, data is globally deduplicated across all repositories.
