Microsoft Official Course ® Module 7 Planning and Implementing Disaster Recovery

Module Overview • Planning for Disaster Mitigation • Planning and Implementing Exchange Server 2013 Backup • Planning and Implementing Exchange Server 2013 Recovery

Lesson 1: Planning for Disaster Mitigation • Identifying Data-Loss Scenarios • Data-Loss Mitigation Features • Planning a Disaster Mitigation Strategy • Discussion: What Is the Relationship Between Disaster Recovery and High Availability? • Exchange Server Native Data Protection • Discussion: When Is Exchange Server Native Data Protection Appropriate? • What Are the Timelines for Disaster Recovery? • Scenarios Requiring Backup and Restore

Identifying Data-Loss Scenarios Data loss scenarios Lost item • Lost mailbox • Lost database • Lost server •

Data-Loss Mitigation Features • Mitigating data loss avoids the need to recover from backup • Data-loss mitigation features include: Deleted item recovery • Single item recovery • In-place hold • Deleted mailbox retention • DAGs • Shadow redundancy •

Planning a Disaster Mitigation Strategy Considerations include: Increase Deleted Item Retention increases database size • Increase Deleted Mailbox Retention increases database size • DAGs may prevent service outages due to lost databases and lost servers • Replay lag time may prevent data corruption on a passive copy in a DAG •

Discussion: What Is the Relationship Between Disaster Recovery and High Availability? • What high-availability features can be used as a first line against a disaster? • What do you achieve if you are using fault- tolerant hardware?

Exchange Server Native Data Protection Exchange Native Data Protection includes the following Exchange Server 2013 features: High availability that minimizes downtime and data loss • Single-item recovery and In-Place hold policies for recovering deleted messages • Point-in-time database recovery with lagged copies of mailbox databases • Archive mailboxes, retention and archive policies, In-place e. Discovery for managing large mailboxes • Exchange Native Data Protection reduces costs by: Simplifying management • Requiring no backup software or hardware • Requiring no RAID •

Discussion: When Is Exchange Server Native Data Protection Appropriate? • Does your organization work with Exchange Server 2010 or 2013 and that uses only Exchange Server Native Data Protection? Why? • Does your organization use traditional backups? Why? • Does your organization use combination of Exchange Server Native Data Protection and traditional backups? Why? • Which features of Exchange Server Native Data Protection do you use in your organization? • In which situation is it appropriate to use only Exchange Server Native Data Protection?

What Are the Timelines for Disaster Recovery? The RTO determines: • How quickly the service is restored The RPO determines: • From what point in time is the disaster recovery performed Based on the RTO and RPO, you might choose to: Keep databases small to shorten restore times • Keep transaction logs on separate drives to ensure they can be replayed after a restore • Backup up every few hours to ensure minimal data is lost •

Scenarios Requiring Backup and Restore Scenarios: Recover a message when single-item recovery is not enabled • Recover a mailbox after the mailbox retention period has passed • Recover a public folder item after the item retention has passed • Recover from a failed database when a DAG is not in use • Recover from a failed server when a DAG is not in use • Backups may be used to meet compliance requirements

Lesson 2: Planning and Implementing Exchange Server 2013 Backup • Backup Requirements for Exchange 2013 • Choosing Exchange Server Backup Software • Choosing Exchange Server Backup Media • How Does a VSS Backup Work? • Demonstration: How to Back Up Exchange Server 2013

Backup Requirements for Exchange 2013 Exchange Server Role Backed-Up Data All roles • System State of server and Active Directory database on domain controllers • Databases and transaction logs • Message tracking logs • Unified Messaging custom audio prompts • Server certificates used for SSL • Specific Internet IIS configuration Mailbox server Client Access server

Choosing Exchange Server Backup Software Windows Server Backup: Runs locally on the computer running Exchange Server • Cannot back up to tape • Restore only full databases • Cannot backup passive DAG copies • DPM: Uses agents on the computer running Exchange Server • Typically backs up to disk and then archives to tape • Can restore databases or mailboxes • Can back up passive DAG copies • Non-Microsoft backup software may be able to: The backup software must support VSS • Restore individual items • Perform brick-level backups •

Choosing Exchange Server Backup Media Description Tape Disk SAN-based Is physically easy to transport and very durable Increases backup performance Backs up the traffic of the main network and keeps it on the SAN

How Does a VSS Backup Work? Exchange 2013 and VSS backup • The VSS writer inside Microsoft Exchange Information Store is moved to the Microsoft Exchange Replication service • Referred now as the Microsoft Exchange Writer • Used by Exchange-aware VSS-based applications to backup and restore active and passive database copies • For backup and restore, the Microsoft Exchange Information Store and the Microsoft Exchange Replication service are required and need to be running

Demonstration: How to Back Up Exchange Server 2013 In this demonstration, you will see how to: • Install the Windows Server Backup program • Use Windows Server Backup to back up Exchange 2013

Lesson 3: Planning and Implementing Exchange Server 2013 Recovery • Options for Recovering Exchange Server Functionality • Options for Recovering Mailbox Data and Databases • Planning the Recovery of Client Access Servers • Repairing Exchange Server Database Corruption • 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

Options for Recovering Exchange Server Functionality To replace lost server roles: Build a new server with equivalent functionality • Add roles to an existing Exchange server • To restore a lost server: Build a new server • Restore system state (optional) • Install Exchange Server with Recovery mode • Restore any necessary data •

Options for Recovering Mailbox Data and Databases • When a database or server fails, you have several options for recovery, including: Options Database restore Recovery database Database portability Dial-tone recovery DAG recovery Description Replaces an existing database Restores database to an alternate location for data recovery Restores database without having to recover a specific server Restores server functionality rapidly before historical mailbox contents are restored Mounts a database copy on a different Exchange server with the mailbox role installed

Planning the Recovery of Mailbox Data and Databases Considerations: Use DAGs to avoid the need to recover • Separate transaction logs and databases • Use a dial-tone database to speed up recovery • Allocate disk space for a recovery database • Use mailbox databases with a smaller size •

Planning the Recovery of Client Access Servers • The basic functions of Client Access servers can be recovered without backup up existing servers • Replace a failed Client Access server by: Adding the server role to an existing Exchange server • Deploying a new server with the same server role • • Replacing and deploying a new server can result in some applications requiring reconfiguration

Repairing Exchange Server Database Corruption • The following cmdlet to repair database corruption is available: • New-Mailbox. Repair. Request • The cmdlet provides the following benefit over isinteg. exe: No need to take the database offline • Runs on Windows Power. Shell, enabling you to automate the process •

Process for Recovering Data Using the Recovery Database A recovery database allows you to: Restore the database from backup • 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 • Create a new Mailbox. Restore. Request

What Is Dial-Tone Recovery? • Dial-tone recovery is the process of implementing access to email services without restoring data to user mailbox • Dial-tone recovery benefits: 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: 1. Create the dial-tone database 2. If necessary, configure the mailboxes that were on the database to use the new dial-tone database 3. Restore the database and log files that you want to recover into the Recovery Database 4. Swap the dial-tone database with the database that you have recovered in the step before 5. Export and import the content from the dial-tone database into the recovered original database
