  1. 1. Module 8 ImplementingBackup and Recovery
  2. 2. Module Overview• Planning Backup and Recovery• Backing Up Exchange Server 2010• Restoring Exchange Server 2010
  3. 3. 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
  4. 4. Discussion: The Importance of Planning forDisaster Recovery• Why is it important to plan for a disaster?• What do you do in your organization to plan for a disaster recovery?
  5. 5. Considerations for Highly Available Mailbox Databases When planning mailbox databases, first determine whether you will deploy standalone mailbox servers or DAGs Your choice will determine how you plan: • Backup policies • Mailbox database size • Database and transaction log locations • Storage solutions
  6. 6. What Is Exchange Native Data Protection?Exchange Native Data Protection includes the followingExchange Server 2010 features: • High availability minimizes downtime and data loss • Single item recovery and litigation hold policies for recovering deleted messages • Point-in-time database recovery with lagged copies of mailbox databases • Archive mailboxes, retention and archive policies, Multi-Mailbox Search for managing large mailboxesSome organization may not be able to use Exchange NativeData Protection because of regulatory or other requirementsthat require to do traditional backups to disk or tape
  7. 7. Disaster Mitigation Options in Exchange Server 2010 Risk Mitigation OptionLoss of a message • Configure recoverable items and deleted item retention settings • Recover messages from backup by using the recovery databaseLoss 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 • Create a DAG on another serveror server • Recover the server from backup • Install Exchange Server with /m:RecoverServerLogical corruption • Create a lagged database copy in a DAGin the database environment • Back up the Exchange Server 2010 data, and recover databaseLoss of a public • Implement public folder replicasfolder database
  8. 8. Demonstration: Recovering Deleted ItemsIn this demonstration, you will see how to configure singleitem recovery so that you can recover a deleted folder withthe Discovery Search Mailbox to the original mailbox
  9. 9. 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
  10. 10. Changes to Backup in Exchange Server 2010Exchange Server 2010 changes that affect the backup ofExchange server databases: • Removal of ESE streaming APIs for backup and restore • Removal of storage groups • Database no longer closely linked to a specific Mailbox serverUsing DAGs, you can have multiple database copies hostedon multiple servers and you can effectively have ExchangeServer organization without traditional backups
  11. 11. Backup Requirements for Exchange Server 2010 Exchange Backed-Up Data Server RoleAll roles • System State of server and Active Directory database on domain controllersMailbox server • Databases and transaction logsClient Access • Server certificates used for SSLserver • Specific IIS configurationTransport servers • Message tracking logsEdge Transport • Content filtering databaseserverUnified • Custom audio promptsMessaging server
  12. 12. 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 Writer: Volume Requestor: VSS writer freezes Shadow Copy Vendor integration write operations Service module for to ensure data Exchange Server consistency Provider (System or Hardware) e.g. storage array Disk 1 Disk 2 Disk 3 Disk 4 Disk 5
  13. 13. Selecting an Exchange Server Backup SolutionWhen selecting a backup solution, consider the following: • System characteristics: • Amount of data to backup, recovery time requirements • Backup software selection: • Windows Server Backup or 3rd Party Backup Tools • Backup hardware selection: • Disk or Tape
  14. 14. Demonstration: How to Back UpExchange Server 2010In 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
  15. 15. 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
  16. 16. Repairing Exchange Database CorruptionSince Exchange Server 2010 SP1, the following cmdlets torepair database corruption are available: • New-MailboxRepairRequest • New-PublicFolderDatabaseRepairRequestThe cmdlets provide the following benefits over isinteg.exe: • No need to take the database offline • Runs on Windows PowerShell , therefore you can automate the process
  17. 17. Restore StrategiesRestore and recovery strategies in Exchange Server 2010include: • Hold policy and Single Item Recovery • Deleted mailbox retention • Database restores • Recovery database • Dial-tone recovery • Recovery server
  18. 18. Process for Recovering Data Using theRecovery Database A recovery database lets you mount a second copy of a mailbox database and extract data 1 Restore the database from backup KJK 2 Create a recovery database 3 Mount the database and extract dataRecovery database scenarios include: • Dial-tone recovery • Individual mailbox recovery • Specific item recovery
  19. 19. Demonstration: How to Recover Data by Usingthe Recovery DatabaseIn this demonstration, you will see how to:• Create the recovery database• Restore data to the recovery database
  20. 20. What Is Dial-Tone Recovery?Dial-tone recovery is the process of implementing access toemail services without restoring data to user mailboxesBenefits of dial-tone recovery: • 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
  21. 21. Process for Implementing Dial-Tone RecoveryProcess for implementing dial-tone recovery: 1 Create the dial-tone database 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
  22. 22. Process for Recovering Computers That RunExchange ServerProcess for recovering computers that run Exchange Server: Install Windows Server 2008, and any service packs and1 software updates, on the computer that you are rebuilding2 Reset the Active Directory computer account for the failed server, and join the computer to the domain3 Run Exchange Server 2010 Setup in Recover Server mode4 Recover the Exchange Server data
  23. 23. 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 informationEstimated time: 75 minutes
  24. 24. Lab ScenarioYou are a messaging administrator for A. Datum Corporation.Your organization has deployed Exchange Server 2010. You nowwant to ensure that all Exchange Server-related data is backedup and that you can restore not only the full server or database,but also a mailbox or mailbox folder.
  25. 25. 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?
  26. 26. Module Review and Takeaways• Review Questions• Common Issues and Troubleshooting Tips• Best Practices
