This white paper discusses the various reasons to archive email and other electronic content. However, it goes beyond that to provide some concrete reasons and justification for deploying and maintaining an archiving system, most of which are based on the cost savings that archiving can provide - both direct cost savings and reduced costs arising from lowered risk. Further, information is also provided on the three sponsors of this white paper: Google, Mimecast and Mimosa Systems - and their relevant archiving solutions.
