Data Deduplication

Disk-based Backup Solution with Byte-level Data De-duplication

ExaGrid is a cost-effective and scalable disk-based backup solution that works with your
existing backup application. ExaGrid combines high quality SATA drives, compression and
data de-duplication for fast and reliable backups and restores. ExaGrid’s innovative approach minimizes the amount of data to be stored by providing standard data compression for the most recent backups, along with byte-level data deduplication for all previous backups. ExaGrid’s byte-level data de-duplication technology stores changes from backup to backup instead of storing full file copies. This unique approach reduces the disk space required by at least 10, and up to 50 to 1, delivering unparalleled cost savings and performance all in a solution that is less than 30% the cost of standard SATA based storage.

Five Core ExaGrid Server Configurations

1TB EX1000 – 2TB EX2000 – 3TB EX3000 – 4TB EX4000 – 5TB EX5000

For example, a 5TB ExaGrid server can store a 5TB full backup (5TB of primary data) plus
up to 16 weeks of retention/history, while a 2TB server can take in a 2TB full backup (2TB
of primary data) plus up to 16 weeks of retention. If a 20TB system is required, then four
EX5000s are plugged into the switch and virtualize into a single system.
