Per estimates made by IDC and EMC (see http://www.emc.com/leadership/digital-universe/2012iview/executive-summary-a-universe-of.htm), digitally created data is expected to double roughly every two years and reach an astounding 40,000 exabytes by 2020. While the cost-per-gigabyte of storage is coming down, it is clearly not keeping up with the rate of data growth. In the data protection domain, the contribution to data growth comes from the need for traditional forms of protection. The 3-2-1 rule summarizes this perfectly—3 copies of data on at least 2 different forms of storage with at least 1 copy that is offsite.
At the same time, other changes are sweeping through the datacenter. Per a study by EMC in 2013 (see https://education.emc.com/content/_common/docs/articles /Managing_Storage_Trends_Challenges_and_Options_2013_2014.pdf), server virtualization reached a critical inflection point in 2012 when the storage deployed for virtualized deployments surpassed the storage deployed for physical deployments. Virtualized deployments will accumulate storage steadily to reach about 50 percent of all storage deployed by 2015, as more and more organizations transition their storage from their physical deployments. Like with any infrastructure inflection, it presents an opportunity for IT decision makers to re-examine their datacenter management tool-chain, and clearly backup technologies are one of the major considerations resulting from this inflection. The other important datacenter trend is that while private and public cloud deployments are on the rise, the majority of deployments are still on-premises. This means infrastructure management technologies such as backup need to support a hybrid deployment environment.
