Database Recovery Using the Recovery Storage Group

A recovery storage group lets you mount a second copy of an Exchange mailbox database and extract dataA recovery storage group lets you mount a second copy of an Exchange mailbox database and extract data

Create a recovery storage group and database

Restore the database that you are recovering

Mount the database and merge the data

Recovery storage group considerations:Recovery storage group considerations:

Logical information about the storage group, database, and mailboxes in the database must be intact and unchanged in Active Directory

You can recover a single mailbox, a single database, or a group of databases in a single storage group

You cannot recover public folder content

The Exchange Server 2007 recovery storage group does not support mounting mailbox databases from previous versions of Exchange Server

You cannot restore entire Exchange servers

Considerations for Using the Recovery Storage Group

Database Recovery Using Database Portability

Database portability means that you can move mailbox databases between Mailbox servers and mount the database without modifying the database or server configuration

Database portability means that you can move mailbox databases between Mailbox servers and mount the database without modifying the database or server configuration

To move a mailbox database to another server:To move a mailbox database to another server:

Perform a soft recovery on the database

Create the destination database on the new server

Move the database files and mount the database

Reconfigure the user mailboxes

Perform a soft recovery on the database

Create the destination database on the new server

Database Recovery Using Local Continuous Replication

Use LCR to recover from a lost or corrupted production database or from failed transaction logsUse LCR to recover from a lost or corrupted production database or from failed transaction logs

Disable LCR on the production storage group

Modify the location used for data storage by the storage group and mailbox database

Mount the database

Disable LCR on the production storage group

Modify the location used for data storage by the storage group and mailbox database

Mount the database

Process for Recovering Public Folder Databases

Configure a recovery server to restore the public folder store

Create an empty public folder database on the recovery server and overwrite it by using the backup set from the production server

Configure a mailbox in the recovery Exchange organization

Mount the restored database and connect to the database using the messaging client

Copy the required public folder data to a .pst file

Copy the individual messages or public folders from the .pst file into the production environment

Lesson 2: Recovering a Messaging Database Using Dial-Tone Recovery

What Is Dial-Tone Recovery?

Process for Implementing Dial-Tone Recovery

Dial-Tone Recovery Scenarios

What Is Dial-Tone Recovery?

Dial-tone recovery benefits:Dial-tone recovery benefits:

Enables users to send and receive e-mail as soon as possible after the loss of a database or server

Dial-tone database can be merged with the recovered database into a single up-to-date mailbox database

Enables users to send and receive e-mail as soon as possible after the loss of a database or server

Dial-tone database can be merged with the recovered database into a single up-to-date mailbox database

Dial-tone recovery is the process of implementing access to e-mail services without restoring data to user mailboxes

Dial-tone recovery is the process of implementing access to e-mail services without restoring data to user mailboxes

Process for Implementing Dial-Tone Recovery

Create the dial-tone database

If necessary, configure the mailboxes that were on the failed database to use the new dial-tone database

If necessary, configure the Outlook client profiles

Restore the failed databases from backup

Merge the data in the two databases

Create the dial-tone database

Dial-Tone Recovery Scenarios

Scenario Recovery Tasks

Same server dial-tone recovery

Configure the dial-tone database on the same Mailbox server as the original database, restore the mailbox database on the same server and merge the two databases

Alternate server dial-tone recovery: option 1

Use an alternative server as a temporary location for the dial-tone mailbox database, but restore the original database on the original server

Alternate server dial-tone recovery: option 2

Implement the dial-tone database on an alternative Mailbox server and permanently move the mailbox database to that server
