Data Deduplication and growing Disk/Storage demand. IDC REPORT – Storage Purchase and expected. Source: IDC Worldwide File-Based Storage 2011-2015 Forecast: Foundation Solutions for Content Delivery, Archiving and Big Data, doc #231910, December 2011 Using DDPEval.exe we can use to evaluate savings with Deduplication without even installing or enabling deduplication.
