When to Dump Stale Electronic Data
"Corporate counsel, IT officers and records managers all have an interest in controlling and expiring stale information -- data that no longer serves a business purpose, or is not subject to a regulatory or legal hold obligation to preserve.
Stale information poses the risk of excess discovery costs while bestowing little benefit. Even when a corporation has been diligent in purging stale information, significant repositories of information may persist outside of its IT infrastructure -- in the hands of its outside counsel.
Since the typewriter era, corporations and law firms have routinely eliminated stale paper through common practices such as an annual file cabinet cleaning day. Culling paper is an intuitive task that can be performed by the employee who keeps the file cabinet -- keeping what is needed, sending records to be filed and disposing of the rest (e.g,. stale documents).
There is an ostrich-like tendency to ignore electronically stored information because the task is not immediately visible as it is with paper -- and ESI storage is relatively inexpensive. Furthermore, executives may not appreciate the associated risks and are unsure how to go about eliminating stale ESI."
