Storage: Rampant Data Duplication Clogs Enterprise Storage Media

By Dick Weisinger

‘Copy Data’ — the storage of duplicated data for safekeeping —  may be the reason behind 85 percent of all hardware purchases that were made in 2012.  That’s the conclusion of a report by IDC.

The report finds that “Maintaining copies of data both locally and geographically and in an online or offline manner is absolutely essential for maintaining service quality. But at some point, this maintenance goes from being an insurance policy to paranoia. IDC expects this paranoia to cost businesses roughly $44 billion in 2013.”

Ashish Nadkarni, analyst at IDC, said that  “as companies come under increased scrutiny for being compliant, meet regulatory laws and IT departments come under increased pressure to maintain service levels, they are increasingly fueling the ‘human instinct’ of being over-protective of their data. This leads to multiple secondaries copies of data.”

The IDC report on Copy Data finds that:

  • 70 percent of enterprises say that because more applications are being used, the amount of data stored is increasing
  • 50 percent of enterprises say that they are storing more backups of application data than in the past
  • 61 percent of enterprise storage media is occupied by duplicate data
  • Enterprises in 2013 have allocated about three quarters of their storage space for holding duplicate data
  • Global spending on ‘Copy Data’ storage will reach $50 billion by 2016 — which will buy more than 300 Exabytes of storage space.  IDC estimates that the dollar spend on ‘Copy Data’ storage will grow at an annual rate of 23.5 percent.

Some of the reasons why enterprises are storing more application copies include increased need to do application development and testing, regulatory compliance, multi-user access, and long-term archival.
