ExaGrid understands that deduplication is required, but how you implement it changes everything in backup. ExaGrid has a unique landing zone where backups can land straight to disk without any inline processing. Backups are fast and the backup window is short. ExaGrid is typically 3X faster for backup ingest. Deduplication and offsite replication occur in parallel with the backups for a strong RPO (recovery point). Deduplication and offsite replication occur in parallel with the backups by using available unused resources. Deduplication and replication never impede the backup process as they always are second order priority. ExaGrid calls this, “adaptive deduplication.” Since backups write directly to the landing zone, the most recent backups are in their full undeduplicated form ready for any request. Local restores, instant VM recoveries, audit copies, tape copies, and all other requests do not require rehydration and are as fast as disk. As an example, instant VM recoveries occur in seconds to minutes versus hours for the inline deduplication approach. ExaGrid provides full appliances (processor, memory, bandwidth, and disk) in a scale-out system. As data grows, all resources are added, including additional landing zone, bandwidth, processor, and memory as well as disk capacity. The backup window stays fixed in length regardless of data growth, which eliminates expensive server upgrades. Unlike the inline, scale-up approach where you need to guess at how much server hardware and storage is required, the ExaGrid approach allows you to simply pay as you grow by adding the appropriate sized appliances as your data grows. ExaGrid has eight appliance models and any size or age appliance can be mixed and matched in a single system, which allows IT departments to buy compute and capacity as they need it. This evergreen approach also eliminates product obsolescence.
ExaGrid thought through data deduplication implementation and created an architecture that provides for the fastest backups, restores, recoveries and tape copies; fixed the backup window as data grows; and eliminated forklift upgrades and obsolescence, while allowing IT staff to buy what they need as they need it. There is no downside and only upside.
ExaGrid has taken the stress out of backup storage with 3X the backup performance, up to 20X the restore and VM boot performance, and a backup window that stays fixed in length as data grows.
