• Recommended best practices for protecting and
recovering Exchange
• Solutions for Exchange available today
• Quest data protection solutions

3. Challenges
• Exponential data growth
• Email is increasingly seen as mission-critical
• Less tolerance for data loss and prolonged downtime
• Increasing number of requests to discover and recover
data from within Exchange

4. Plan for The Unexpected
• Server Failure • Single Mail Item Loss
– OS failure, hardware failure – A user inadvertently hard-
deletes an important mail item
• Database Failure
– Database corruption or disk • Site Disaster
failure – Power outage, network
outage, natural disaster
• Single Mailbox Loss
– A mailbox is deleted and needs
to be recovered

5. Gather Organizational Requirements
• Measure the value your organization places on its
email data
• What are the acceptable levels of data loss?
• What is the acceptable length of time for service and
data restoration?
• Where are my Exchange Servers located?

7. Set Recovery Objectives
• Recovery Time Objective (RTO)
– The amount of time elapsed between a loss or disaster and the
restoration of business operations. It is the time required to physically
recover the data or application and have it ready for use
• Recovery Point Objective (RPO)
– The point in time that recovered data will be recovered to.
– For example, if you recover a file that was backed up yesterday then
your recovery point is one day

8. Create a Service Level Agreement (SLA)
• Obtain agreement on objectives in the form of a SLA
• Include the following categories:
– Availability
– Hours of operation
– Performance measures
– Recovery parameters
– Support parameters
– Environmental dependencies and assumptions

9. Protecting Exchange
Your protection strategy
should directly support your
recovery requirements

10. High Availability
• Database Availability Groups (DAG)
– New framework introduced in Exchange 2010
– A group of mailbox servers (up to 16) that replicate to one another,
providing database-level protection from outages
– Uses Exchange Continuous Replication (logs shipping) and a subset of
Windows failover clustering technologies to provide continuous HA and
site resiliency

11. Backup
• Traditional Backup
– Protection for information stores, individual storage groups, or
individual databases
– Enterprise protection for heterogeneous environments (centralized
management and monitoring)
– Target disk or tape
• Real-time Backup (Continuous Data Protection)
– Watches all changes occurring during a defined period
– An initial sync/seed of the data to be protected is created
– All changes that occur after the initial sync/seed are captured and
available for restore

12. Disaster Recovery
• Host-Based Replication
– Cross-platform replication for applications like Microsoft Exchange, as
well as Microsoft SQL, MySQL, and PostgreSQL residing in
Windows, Linux, Solaris and Mac OS X environments
– Centralized management and monitoring of replication
• Replication of Backup Copies
– Replicates changes to protected datasets from one (or many) backup
servers to another backup server

13. Recovering Exchange
Clearly document and test
recovery strategy to minimize
the chance for mistakes

14. Elements of a Restore Strategy
Include the following in your restore strategy:
• Build a communications plan
– Identify the personnel involved in disaster recovery efforts, their
responsibilities and chain of command
• Set restore priorities
– Prioritize what should be restored
• Provision a ―dial-tone‖ system
– Allow users to send and receive new email before the historical email
data has been fully restored
• Restore type
– Use the recovery storage group to restore the data and merge the
restored data into the ―dial-tone‖ database
