What is De-Duplication and How Do I Do It?

When collecting electronically stored information (“ESI”) from multiple custodians (i.e., various individuals/ different sources), there will necessarily be duplicative documents collected in the process.  In company-wide e-mail chains, for example, a message is sent to multiple recipients and stored within each recipient’s mailbox.  Consider the following: I send an email to two colleagues; a copy of the very same email now exists in each colleague’s mailbox.  Depending on the company’s data retention policies, copies of that same e-mail file may also reside on the employee’s (or employees’) hard drive(s), the company’s file server, and/or the company’s backup system.
