ExaGrid's disk backup with deduplication system is the only solution purpose-built for backup that leverages a unique architecture optimized for scalability, performance, and price. The system scales as needed by adding ExaGrid appliances, which virtualize into a GRID architecture automatically, adding capacity and processing power while acting and being managed as one unified system.
ExaGrid provides Tiered Backup Storage with a unique disk-cache Landing Zone, non-network-facing long-term retention repository, and scale-out architecture. ExaGrid’s Landing Zone provides for the fastest backups, restores, and instant VM recoveries. The disk-cache Landing Zone tier allows for the fastest backups and restores. The Repository Tier offers the lowest cost for long-term retention and a non-networkfacing tier to be able to recover from security attacks, such as ransomware. ExaGrid’s scale-out architecture includes full appliances and ensures a fixed-length backup window as data grows, eliminating expensive forklift upgrades and planned product obsolescence.
ExaGrid Tiered Backup Storage makes backup better with:
- Fastest backups resulting in the shortest backup window
- Fastest restores
- Instant VM recoveries in seconds to minutes
- Fastest offsite tape copies, copy jobs, and AUX copies
- A fixed-length backup window as data grows, eliminating expensive future forklift upgrades
- Retention Time-Lock (RTL) to ensure recovery from a ransomware attack – non-networkfacing tier creates a tiered air gap
- Industry-leading deduplication ratios for storing long-term retention data for low-cost retention storage
- Deduplication efficiency across the entire system with global deduplication
- Further deduplicates data already deduplicated by the backup application
- Virtualized storage efficiency with automatic load balancing
- Fast, reliable, and up-to-date offsite disaster recovery using Adaptive Deduplication
- Linear scalability – scale-out architecture – pay as you grow
- Low cost up front and over time as data grows
- No forklift upgrades or planned product obsolescence
ExaGrid Basic Concept
ExaGrid appliances work seamlessly with over 25 industry-leading backup applications and database utilities by presenting themselves as standard NAS shares (CIFS or NFS), a Veeam Data Mover target, Veritas NetBackup OST target, or as an S3 object store. ExaGrid appliances are easily integrated into existing backup environments, as illustrated below.
ExaGrid sits behind the existing backup server and replaces straight disk, inline deduplication appliances or tape backup storage, both onsite and offsite.

ExaGrid Technology Overview
ExaGrid Appliances Connect to Form a Single Scale-Out System
ExaGrid appliances are comprised of processors, memory, networking, IPMI, RAID 6, and a hot spare drive per appliance, using enterprise-class SAS drives and ExaGrid software. See the ExaGrid Technical Specifications data sheet for more details.
Each appliance plugs in and is virtualized into a shared system with a single user interface, global deduplication, and automatic load balancing. The media server is connected to the same network and sees the appliances as one or more NAS shares, Veeam Data Mover targets, Veritas NetBackup OST targets, or S3 Object Storage. Since each appliance includes the appropriate amount of processor, memory, Landing Zone disk, deduplicated repository disk, and bandwidth for the rated data size, performance increases as more appliances are added to the system.
