With analyst house IDC predicting that e-mail traffic will reach 35 million messages a day by 2005, and data retention legislation such as the US' Sarbanes Oxley Act making storage a business priority, the costs of keeping e-mails is set keep rising.
A survey of IT directors has found that e-mail storage now makes up around 40 percent of data retention costs in businesses in Europe, the Middle East and Africa, with IT heads reckoning that 20 percent of all the e-mails they have to keep are personal or non-work-related messages.
Out of the 630 IT directors questioned by Hitachi Data Systems, 10 percent thought that e-mails were making up 40 percent of their total storage capacity, with another quarter believing that e-mails are adding up to 20 percent of their entire storage.
