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 • Considerations for Highly Available Mailbox Databases• What Is Exchange Native Data Protection?• Disaster Mitigation Options in Exchange Server 2010• Demonstration: Recovering Deleted Items
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?
Considerations for Highly Available Mailbox Databases
• Mailbox database size
• Backup policies
• Database and transaction log locations
Your choice will determine how you plan:
• Storage solutions
When planning mailbox databases, first determine whether you will deploy standalone mailbox servers or DAGs
What Is Exchange Native Data Protection?
Exchange Native Data Protection includes the following Exchange Server 2010 features:
• High availability minimizes downtime and data loss
• Point-in-time database recovery with lagged copies of mailbox databases
• Single item recovery and litigation hold policies for recovering deleted messages
• Archive mailboxes, retention and archive policies, Multi-Mailbox Search for managing large mailboxes
Some organization may not be able to use Exchange Native Data Protection because of regulatory or other requirements that require to do traditional backups to disk or tape
Disaster Mitigation Options in Exchange Server 2010Risk Mitigation Option
Loss of a message • Configure recoverable items and deleted item retention settings
• Recover messages from backup by using the recovery database
Loss of a mailbox • Configure and use mailbox retention settings• Back up the Exchange Server 2010 data, and
recover database to a recover databaseLoss of a database or server
• Create a DAG on another server• Recover the server from backup• Install Exchange Server with /m:RecoverServer
Logical corruption in the database
• Create a lagged database copy in a DAG environment
• Back up the Exchange Server 2010 data, and recover database
Loss of a public folder database
• Implement public folder replicas
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
Lesson 2: Backing Up Exchange Server 2010• Changes to Backup in Exchange Server 2010• Backup Requirements for Exchange Server 2010• How Does a VSS Backup Work? • 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 Exchange Server organization without traditional backups
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
How Does a VSS Backup Work?
Disk 2Disk 1 Disk 3 Disk 4 Disk 5
Writer: VSS writer freezes write operations to ensure data consistency
Requestor:Vendor integration module for Exchange Server
Volume Shadow Copy
Service
Provider (System or Hardware)
e.g. storage array
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
Selecting an Exchange Server Backup Solution
When selecting a backup solution, consider the following:
• Backup software selection:• Windows Server Backup or 3rd Party Backup Tools
• System characteristics:• Amount of data to backup, recovery time requirements
• Backup hardware selection:• Disk or Tape
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• Repairing Exchange Database Corruption• 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• Process for Recovering Computers That Run Exchange
Server
Repairing Exchange Database Corruption Since Exchange Server 2010 SP1, the following cmdlets to repair database corruption are available:
• New-PublicFolderDatabaseRepairRequest
• New-MailboxRepairRequest
The cmdlets provide the following benefits over isinteg.exe:
• Runs on Windows PowerShell , therefore you can automate the process
• No need to take the database offline
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
A recovery database lets you mount a second copy of a mailbox database and extract data
Restore the database from backupKJK
Create a recovery database Mount the database and extract data

Demonstration: How to Recover Data by Using the Recovery DatabaseIn 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 email services without restoring data to user mailboxes
• Enables users to send and receive email 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
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
Merge the data in the two databases
Restore the failed databases from backup

Process for Recovering Computers That Run Exchange Server
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

Lab: Implementing Backup and Recovery • Exercise 1: Backing Up Exchange Server 2010 • Exercise 2: Restoring Exchange Server Data • Exercise 3: Restoring Exchange Servers (optional)
Logon information
Estimated time: 75 minutes
Lab ScenarioYou 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.
Lab Review• What backup options can you use to recover a single
mailbox? • Which Exchange Server 2010 technology would you use to
create a database backup at a remote site? • What is VSS? • What is dial-tone recovery?
