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

• 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
