High Performance, Scalable Disk Backup with Data Deduplication

ExaGrid is a scalable, cost-effective disk-based backup with deduplication solution that revolutionizes how organizations back up and protect their data.

With ExaGrid, you get the only disk backup appliance purpose-built for backup that leverages a unique architecture optimized for backup and restore performance, scalability, and price. Only ExaGrid's performance-based GRID architecture offers you:

  • Fastest backups up front with permanently short backup windows as data grows
  • Instant recovery of full systems, VMs, and files so you have the least downtime
  • Lowest total cost over time by eliminating "forklift" upgrades and product obsolescence

Our patented zone-level deduplication reduces the disk space needed by a range of 10:1 to 50:1 by storing only the unique bytes across backups instead of redundant data. Post-process deduplication delivers the fastest backups, and as your data grows, only ExaGrid avoids expanding backup windows by adding full servers in a GRID. ExaGrid's unique landing zone keeps a full copy of the most recent backup on disk, delivering the fastest restores, instant VM recovery, "Instant DR," and fast tape copy. And, as data grows, ExaGrid saves you 50% in total system costs compared to competitive solutions by avoiding costly "forklift" upgrades.

Replace Tape with Cost-Effective Disk-Based Data Protection

Using ExaGrid's disk backup solution to replace tape in the nightly backup process can reduce backup windows by up to 90%. A typical 12-hour backup window can be decreased to as little as two to three hours. ExaGrid improves the speed and reliability of your backups and restores, including support for advanced virtualized server recovery techniques such as instant VM recovery. For offsite long-term retention or disaster recovery, ExaGrid offers the ability to transfer backup data to an installed system at a remote location to supplement or eliminate offsite tapes. ExaGrid also supports multi-site topologies where multiple locations can transfer backup data to a centralized site for DR protection. ExaGrid is very cost effective at transferring backup data offsite because ExaGrid's deduplication only moves changes, requiring minimal WAN bandwidth. The costs and reliability issues associated with tape handling, shipment, and storage are significantly reduced or eliminated.

ExaGrid Appliance

The ExaGrid system includes standard appliances along with ExaGrid's software to deliver a complete turnkey solution for disk backup with data deduplication. The ExaGrid appliance is rack-mountable and uses standard components, including Intel® processors, enterprise SATA/SAS drives, and Gigabit Ethernet connection(s).

ExaGrid works seamlessly with all popular backup applications, so you can preserve your investment in backup applications and processes. Using ExaGrid is as simple as pointing your existing backup jobs to a NAS share on the ExaGrid appliance. Backup jobs are sent directly from the backup application to the ExaGrid appliance for onsite disk backup. The backup application can create copies from the ExaGrid system directly to your tape library for offsite storage, or you can deploy a second site ExaGrid to reduce or replace offsite tape.

Highest Performance for Backups

  • Fastest backup performance using post-process deduplication, so nothing interferes with the data writing directly to disk, at the speed of disk
  • Backup windows kept permanently short as data grows by adding full servers (with processor, memory, disk, and bandwidth) in a GRID

Fastest Restores and Instant Recovery

  • Fastest restore and tape copy performance from the most recent backup kept in its whole form. No reassembly from small blocks and large hash tables is required.
  • Instant recovery of VMs from high-speed landing zone, which maintains a full copy of the latest backup. If the primary VM is unavailable, recover and run a VM from the ExaGrid system within minutes.

Most Cost-Effective Solution with No "Forklift" Upgrades

  • Scalable next-generation GRID architecture with full servers provides plug-and-play expansion. To add an ExaGrid appliance, you simply plug it in and let ExaGrid's GRID software virtualize the backup capacity pool.
  • Multiple appliances allow full backups of 1TB, 2TB, 3TB, 4TB, 5TB, 7TB, 10TB, 13TB, or 21TB with corresponding raw capacity of 5TB, 7TB, 9TB, 11TB, 13TB, 16TB, 26TB, 32TB, and 48TB, respectively. Any size appliance can be mixed and matched in multiple different configurations with up to ten servers combined into a single GRID of up to 480TB raw capacity, allowing full backups of up to 210TB.
  • 50% lower total system cost vs competing systems over time by eliminating the costly "forklift" upgrades associated with a first-generation front-end controller/disk shelf architecture.

Our data has grown tremendously in the past four years – we never could have backed it all up to tape.
