Storage Company of the Year
Entry Description
ExaGrid offers the largest backup storage system in the industry, with the best backup performance; its backup speeds are three times faster than traditional dedupe appliances, and the ability to restore data 20 times faster. In addition, ExaGrid’s unique Tiered Backup Storage architecture also offers the most cost-effective solution for long-term retention. ExaGrid provides its customers with a scalable backup storage solution that supports more than 25 backup applications and utilities, protecting an organization’s investment in its existing backup environment while offering flexibility for future plans to change or add backup processes.

ExaGrid’s Unique Approach: Tiered Backup Storage

Disk-cache Landing Zone (Performance Tier)
• ExaGrid writes directly to disk for the fastest backup performance
• ExaGrid restores directly from disk for the fastest restores and VM boots

Long-term Retention Repository (Retention Tier)
• ExaGrid tiers long-term retention to a deduplicated data repository to reduce storage and resulting storage costs

Backing up to low-cost disk is fast for backups and restores, however, with longer-term retention, the amount of disk required becomes extremely expensive.

To reduce the amount of disk for long-term retention, deduplication appliances reduce the amount of storage and cost, however the deduplication is performed inline on the way to the disk which slows down backups to about one-third the performance of disk. Also, the data is only stored in deduplicated format resulting in extremely slow restores and VM boots as the data has to be reassembled, or rehydrated, for each request. In addition, deduplication appliances are scale-up storage which only adds storage capacity as data grows, resulting in backup windows that continue to grow as data grows, expensive forklift upgrades, and forced product obsolescence.

ExaGrid Tiered Backup Storage writes directly to disk for the fastest backups, and restores directly from disk for the fastest restores and VM boots. ExaGrid then tiers the long-term retention data to a deduplicated data repository to reduce the amount of retention storage and resulting cost. In addition, ExaGrid provides a scale-out architecture where appliances are simply added as data grows. Each appliance includes processor, memory, and network ports, so as data grows, all resources required are available to maintain a fixed-length backup window. This scale-out storage approach eliminates expensive forklift upgrades, and allows for mixing appliances of different sizes and models in the same scale-out system which eliminates product obsolescence while protecting IT investments up front and over time.

ExaGrid offers the best of both worlds by offering low-cost disk for the fastest backup and restore performance tiered to a deduplicated data repository for the lowest cost retention storage. The scale-out storage architecture provides a fixed-length backup window and is low cost up front and over time.
