By 2010, the amount of data added annually to computer systems worldwide will swell to 988 exabytes, according to an 2007 EMC-sponsored report from IDC. A 2008 update on the report found that in 2007, the digital universe measured 281 billion gigabytes — 281 exabytes — an increase 10 percent greater than analysts had predicted a year earlier. While roughly 70 percent of the data generated in the digital universe is created by individuals, enterprises are responsible for the security, privacy, reliability and compliance of 85 percent of it.
