Store and purge

The day that information turns seven years old, data managers often burn, shred and destroy every trace of that message. But why go to such extremes when storage is so cheap? Simple. Firms are simply obeying the letter of the law, meaning that after seven years – or the period mandated for storing the specific data – accessing that information is not only a burden on a firm's data infrastructure, it also potentially exposes the organisation to various liabilities, audits and subpoenas.
