According to Gartner's report titled Market Trends: E-mail Archiving Strong Growth Continues Autonomy achieved growth of 18.1% from 2008 to 2009 and market share of 23.7% in 2009.

Regarding the prospects for the email archiving market, Gartner states, The e-mail archiving software market saw 13.2% year-over-year growth in 2009. Although this is down from the 2008 growth rate of 25.7%, e-mail archiving is still among the fastest-growing segments of the software market.
