A recovery storage group (RSG) is a special storage group that allows you to mount mailbox databases and extract data from those databases. RSGs enable you to recover data from a backup or copy of a database without disturbing user access to current data.

RSGs have been improved in Microsoft Exchange Server 2007, most notably, in the following areas:

  • RSGs are created and managed by using the Exchange Management Shell, or by using the Exchange Server Disaster Recovery Analyzer Tool (ExDRA). Management of an RSG cannot be performed using the Exchange Management Console.
  • RSGs are not visible in the Exchange Management Console, even after they have been created and populated with a database.
  • ExDRA will prescriptively recommend and then assist in performing recoveries involving a recovery storage group.

The following topics cover the recovery storage group in greater detail:
