Discussion: The Importance of Planning for
Disaster Recovery
• Why is it important to plan for a disaster?
• What do you do in your organization to plan for a disaster
recovery?
Integrating High Availability and Disaster Recovery
High availability integrates with disaster recovery as
follows:
• Link between high availability and disaster recovery
• High availability options beyond traditional backup and
restore
• Large mailbox considerations
Even in a highly available deployment, backup and recovery
might still be necessary for maintaining your Exchange
Server 2010 environment
Disaster Mitigation Options in Exchange
Server 2010
Risk
Loss of a message
Loss of a mailbox
Loss of a database
or server
Logical corruption
in the database
Mitigation Option
• Configure recoverable items folder and deleted
item retention settings
• Recover messages from backup by using the
recovery database
• Configure and use mailbox retention settings
• Configure hold policy, and recover it
• Back up the Exchange Server data, and recover
database to a recover database
• Create a DAG on another server
• Recover the server from backup
• Install Exchange with /m:RecoverServer option
• Create a lagged database copy in a DAG
environment
• Backup the Exchange Server data, and recover
database
Demonstration: Recovering Deleted Items
In this demonstration, you will see how to configure
single item recovery so that you can recover a
deleted folder with the Discovery Search Mailbox to
the original mailbox
Disaster Recovery Options for Mailbox Servers
Exchange Server 2010 provides the following disaster
recovery features for Mailbox servers:
• Disaster recovery with DAGs
• Mailbox servers in a DAG can host other server roles
• Point-in-time database snapshot with lagged copy of
DAG
• Recovery database to recover mailboxes, folders, or
items
• Lower cost of DAG backup compared to existing backup
Demonstration: How to Create a Point-in-Time
Database Snapshot
In this demonstration, you will see how to:
• Configure a database copy to a remote server
• Configure the database copy to be a lag database of one
week
• Disable activation on the remote server
Backup and Restore Scenarios
Requirements that may necessitate using traditional backup
methods:
• No available DAGs
• Single Exchange Server implementation
• Utilize an existing backup environment
• Backups are governed by compliance requirements
Lesson 2: Backing Up Exchange Server 2010
• Changes to Backup in Exchange Server 2010
• Backup Requirements for Exchange Server 2010
• Backup Strategies
• How Does a VSS Backup Work?
• Considerations for Selecting an Exchange Server Backup
Solution
• Demonstration: How to Back Up Exchange Server 2010
Changes to Backup in Exchange Server 2010
Exchange Server 2010 changes that affect the backup of
Exchange server databases:
• Removal of ESE streaming APIs for backup and restore
• Removal of storage groups
• Database no longer closely linked to a specific Mailbox
server
Using DAGs, you can have multiple database copies hosted
on multiple servers and you can effectively have a backupless Exchange Server organization
Backup Requirements for Exchange Server 2010
Exchange
Server Role
Backed-Up Data
All roles
• System State of server and Active Directory
Mailbox server
• Databases and transaction logs
Client Access
server
• Server certificates used for SSL
• Specific IIS configuration
database on domain controllers
Transport servers • Message tracking logs
Edge Transport
server
• Content filtering database
Unified
Messaging server
• Custom audio prompts
Backup Strategies
Strategy
Description
Full backup
A full backup performs an online backup of both
the database files and transaction logs
Full plus
incremental
An incremental backup captures only the data that
has changed since the last full or incremental
backup
Full plus
differential
A differential backup captures only the data that
has changed since the last full backup
Copy backup
A copy backup copies entire databases
Brick-level
backups
A brick-level backup copies each message in each
mailbox
How Does a VSS Backup Work?
VSS:
• Produces consistent shadow copies by coordinating
with business applications, file-system services,
backup applications, and storage hardware
• VSS consists of a writer, a requestor, and a provider
Requestor:
Vendor integration
module for
Exchange Server
Volume
Shadow Copy
Service
Writer:
VSS writer freezes
write operations
to ensure data
consistency
Provider (System
or Hardware)
e.g. storage array
Disk 1
Disk 2
Disk 3
Disk 4
Disk 5
Considerations for Selecting an Exchange Server
Backup Solution
When selecting a backup solution, consider the following:
• System characteristics
• Backup software selection
• Backup hardware selection
Demonstration: How to Back Up Exchange
Server 2010
In this demonstration, you will see how to:
• Install Windows Server Backup
• Use Windows Server Backup to backup Exchange
Server 2010
• Use Event Viewer to verify backup of Exchange Server
databases
Lesson 3: Restoring Exchange Server 2010
• Restore Strategies
• Process for Recovering Data Using the Recovery Database
• Demonstration: How to Recover Data by Using the
Recovery Database
• What Is Dial-Tone Recovery?
• Process for Implementing Dial-Tone Recovery
• What Is Database Mobility?
• Process for Recovering Computers That Run Exchange
Server
Restore Strategies
Restore and recovery strategies in Exchange Server 2010
include:
• Hold policy and Single Item Recovery
• Deleted mailbox retention
• Database restores
• Recovery database
• Dial-tone recovery
• Recovery server
Process for Recovering Data Using the Recovery
Database
A recovery database lets you mount a second copy of a
mailbox database and extract data
1 Create a recovery database
KJK
2 Restore the database from backup
3 Mount the database and extract data
Recovery database scenarios include:
• Dial-tone recovery
• Individual mailbox recovery
• Specific item recovery
Demonstration: How to Recover Data by Using
the Recovery Database
In this demonstration, you will see how to:
• Create the recovery database
• Restore data to the recovery database
What Is Dial-Tone Recovery?
Dial-tone recovery is the process of implementing access to
e-mail services without restoring data to user mailboxes
Benefits of dial-tone recovery:
• 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
Process for Implementing Dial-Tone Recovery
1 Create the dial-tone database
5
2
If necessary, configure the mailboxes that were
on the failed database to use the new dial-tone database
3 If necessary, configure the Outlook client profiles
4 Restore the failed databases from backup
5 Merge the data in the two databases
What Is Database Mobility?
Database mobility enables you to move mailbox databases
between Mailbox servers
To move a mailbox database to another server:
• Perform a soft recovery on the database
• Create the destination mailbox database
• Move the database files and mount the database
• Reconfigure the user mailboxes
Process for Recovering Computers That Run
Exchange Server
1 Install Windows Server 2008, and any service packs and
software updates, on the computer that you are rebuilding
2
Reset the Active Directory computer account for the
failed server, and join the computer to the domain
3 Run Exchange Server 2010 Setup in Recover Server mode
4 Recover the Exchange Server data

Lab Scenario
You are a messaging administrator for A. Datum Corporation.
Your organization has deployed Exchange Server 2010. You now
want to ensure that all Exchange Server-related data is backed
up and that you can restore not only the full server or database,
but also a mailbox or mailbox folder.
