It's no secret that we love to back-up our important data. We make copies of our data at home and at work and even have systems that automate the back-up process for us through devices such as NAS' and such. So many copies that we really don't get the full scope of it until a report like the one published today by IDC comes out.
Laura DuBois, Natalya Yezhkova and Ashish Nadkarni all analysts at IDC corp, published a report today called The Copy Data Problem, which cites that for every 10TB of storage, 6TB is used for backups.
Based on the approach presented in this document, IDC estimates that in 2012, more than 60% of enterprise disk storage systems capacity may have been made of copy data. Similarly, in 2012, copy data made up nearly 85% of hardware purchases and 65% of storage infrastructure software revenue. In other words, 6TB out of every 10TB of disk storage systems capacity procured and deployed is allocated to copies of primary data.
