The document is an ExaGrid data sheet that provides information on ExaGrid's disk-based backup appliance configurations. It summarizes that ExaGrid appliances reduce disk space needs by 10-50x through data deduplication, shorten backup windows by 30-90%, and scale easily and cost-effectively with data growth. The appliances can be combined into a GRID configuration of up to 320TB capacity to fully backup up to 130TB of data.
