These snapshots also allow regular scheduled backups to tapes for archival
purposes. With the enhancements in Exchange 2003 and the wealth of
recovery features provided in iTX, recovery of mail store has become very
easy. The main benefit here is that there is no need for a spare disaster
recovery server in its own Active Directory forest to recover a single mailbox
or single mailbox store, as was required in Exchange 2000. The Recovery
Storage Group (RSG) is a new type of storage group in Exchange 2003 that
essentially allows mounting a copy of a mailbox store onto the running
production Exchange 2003 server. Data can be recovered within the restored
mailbox store whilst the current store is still running. Use of the RSG on a
production server does not interfere with the users as the RSG is logically
isolated; users cannot log into it, and mail cannot be delivered to it.
Now let us consider some common recovery scenarios. Let us assume that
some important mails have been accidentally deleted and purged from the
production server.
Open up „Flashback‟ and the recovery wizard will guide you through to the
appropriate snapped image. Once selected, this will create a writable version
of the snapshot which can be connected to the Recovery Storage group on
the same server.
