There are a number of backup, restore, and recovery procedures for Microsoft Exchange Server 2007. For a definition of back up, restore, and recovery, see Disaster Recovery Terminology.
The following areas are covered in this section:
- Server recovery and restore In the
event of a server loss, you have options depending on the server
role and your disaster recovery plan. Server loss could be caused
by software or hardware failure, or by the physical loss of the
site where the server was housed. For information about recovering
from a server loss, see How to Recover a Lost
Exchange Server.
- Edge Transport server recovery The Edge
Transport server does not rely on a remote copy of
Active Directory for storage of its configuration or directory
service information. Instead, the Edge Transport server relies on a
local copy of Active Directory using Active Directory
application mode. Included in the Exchange 2007 installation
files is a set of scripts that allow you to back up and restore
this information. For more information about how to back up and
restore an Edge Transport server, see Using Cloned
Configuration Tasks for Edge Transport Server Disaster
Recovery.

- Mailbox and public folder database backup, restore, and
recovery The mailbox and public folder
databases are the primary storage databases for end-user data in an
Exchange organization. Protecting and recovering these databases
are some of the primary focuses of disaster recovery planning for
Exchange. The following topics explain how to back up, restore, and
recover your Exchange data in a variety of situations:
- Deleted mailbox and deleted item
retention Exchange 2007 supports both
deleted mailbox and deleted item retention. Mailboxes and deleted
items are, by default, held for a number of days in the database.
Covered in the Configuring Deleted
Mailbox and Deleted Item Retention section is how to configure
these settings and how to restore the deleted objects.
- Recovery storage groups Recovery
storage groups are special administrative storage groups. Use the
recovery storage group to recover deleted items or mailboxes from
backup when they are no longer in retention. For more information
about working with recovery storage groups, see Recovery Storage
Groups.
- Queue database on a transport server In
Exchange 2007, all inbound and outbound Simple Mail Transfer
Protocol (SMTP) e-mail messages temporarily travel through an
Extensible Storage Engine (ESE) database called mail.que as
they are processed by the transport server. Queues
exist only on computers that have the Hub Transport server role or
Edge Transport server role installed. Working with the Queue
Database on Transport Servers provides you with
information about how to repair, defragment, and drain the mail.que
database.
