In my frequent discussions with customers about the benefits of cloud archiving for regulatory, legal, abd business reasons, I still find a large percentage that still don't worry about archiving corporate social media content.
It may surprise you to know that 10%, 20%, or even 30% of enterprise data can be classified as grey or inactive data, mainly from ex-employees, that has accumulated over the years as employees left the company. Many organizations simply haven’t defined policies around what to do with departing employee data. A minority of organizations will remove the hard disk from the departing employee’s laptop or desktop computer and place it in a cabinet for a year or longer. This policy is usually driven by the corporate legal department just in case the employee later files a wrongful termination lawsuit. This process is an attempt to address the issue but doesn’t really take into account the other possible data repositories where employee data can reside including file systems, email systems, email archives, removable media, or cloud repositories.
