Module 8 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: • 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: 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 Virtual machines 10135A-VAN-DC1 10135A-VAN-EX1 10135A-VAN-SVR1 User name Administrator Password Pa$$w0rd Estimated time: 75 minutes 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. 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?
