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

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 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?
