Implementing Backup and Recovery
Module Overview
• Planning Backup and Recovery
• Backing Up Exchange Server 2010
• Restoring Exchange Server 2010
Lesson 1: Planning Backup and Recovery
• Discussion: The Importance of Planning for Disaster Recovery
• Integrating High Availability and Disaster Recovery
• Disaster Mitigation Options in Exchange Server 2010
• Demonstration: Recovering Deleted Items
• Disaster Recovery Options for Mailbox Servers
• Demonstration: How to Create a Point-in-Time Database Snapshot
• Backup and Restore Scenarios
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:
• Large mailbox considerations
• High availability options beyond traditional backup and restore
Even in a highly available deployment, backup and recovery might still be necessary for maintaining your Exchange Server 2010 environment
Even in a highly available deployment, backup and recovery might still be necessary for maintaining your Exchange Server 2010 environment
• Link between high availability and disaster recovery
Disaster Mitigation Options in Exchange Server 2010
Risk Mitigation Option
Loss of a message • Configure recoverable items folder and deleted item retention settings
• Recover messages from backup by using the recovery database
Loss of a mailbox • 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
Loss of a database or server
• Create a DAG on another server• Recover the server from backup• Install Exchange with /m:RecoverServer option
Logical corruption in the database
• 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
• Point-in-time database snapshot with lagged copy of DAG
• Mailbox servers in a DAG can host other server roles
• 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
• Utilize an existing backup environment
• Single Exchange Server implementation
• 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 backup-less Exchange Server organization

Backup Requirements for Exchange Server 2010
Exchange Server Role
Backed-Up Data
All roles • System State of server and Active Directory database on domain controllers
Mailbox server • Databases and transaction logs
Client Access server
• Server certificates used for SSL• Specific IIS configuration
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
Considerations for Selecting an Exchange Server Backup Solution
When selecting a backup solution, consider the following:
• Backup software selection
• System characteristics
• 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
• Recovery database
• Dial-tone recovery
• Recovery server
• Database restores
Process for Recovering Data Using the Recovery Database
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?
Benefits of dial-tone recovery:
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
• 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
Create the dial-tone database 5
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

What Is Database Mobility?
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
Database mobility enables you to move mailbox databases between Mailbox serversDatabase mobility enables you to move mailbox databases between Mailbox servers
Process for Recovering Computers That Run Exchange Server
Install Windows Server 2008, and any service packs and software updates, on the computer that you are rebuilding
Reset the Active Directory computer account for the failed server, and join the computer to the domain
Run Exchange Server 2010 Setup in Recover Server mode
Recover the Exchange Server data
