Va. Code § 19.2-267.2
When a subpoena has been served pursuant to Rule 3A:12 of the Rules of the Supreme Court on a person who is not a party to the action requiring the production of information that is stored in an electronic format, the person shall produce a tangible copy of the information. If a tangible copy cannot be produced, the person shall permit the parties to review the information on a computer or by electronic means during normal business hours, provided that the information can be accessed and isolated. If a tangible copy cannot reasonably be produced and the information is commingled with information other than that requested in the subpoena and cannot reasonably be isolated, the person may file a motion for a protective order or motion to quash.
