Windows Server Backup Overview
Windows Server Backup is a feature of the Windows Server®
2008 operating system, that backs up and recovers the
operating system, and restores files and folders that are
stored on the server
With Windows Server Backup, you can:
• Protect your entire server without using separate
backup and recovery technology
• Back up an entire server or selected volumes
• Use the wizards, tools, and the Complete PC Restore
feature to assist in recovering a server
• Set up an automatic backup schedule
• Recover items or entire volumes

Who Can Back Up Data?
• By default, members in the following groups can backup
and restore data on a server:
• Administrators
• Server Operators
• Backup Operators
• To increase security, consider using custom groups that
separate the backup and restore User Rights Assignments
• Limit the number of users that belong to the default
groups with backup/restore rights
4
What Is System State Data?
Component
When is this component
included in System State?
Registry
Always
COM+ Class Registration database
Always
Boot files, including the system files Always
Active Directory Certificate Services
database
If it is a Certificate Services server
Active Directory Domain Services
database
If it is a domain controller
SYSVOL directory
Only if it is a domain controller
Cluster service information
If it is within a cluster
IIS configuration files
If it is installed
System files that are under
Windows Resource Protection
Always

Optimizing Backup Performance
6
Specifying a Backup Time
Back up the entire server
or specific volumes only
Run Backup daily or
more often
7
How Is Data Restored?
8
What Are Shadow Copies?
• Shadow copies provide iterative versions of network folders
• Use shadow copies to:
• Recover files
• Review previous versions
• Shadow copies are:
• Enabled per volume
• Not a replacement for regular backups
• Allocated storage limits versions
9
Shadow Copy Scheduling
• Default schedule is
7:00 A.M. and noon
• Create a shadow copy
schedule based on:
• Volume of changes
• Importance of changes
• Storage limitations
• Test a schedule with a
small group
10
Managing Shadow Copies from a Client Perspective
Shadow copies from the client perspective:
• Windows XP and Windows 2000 Client computers
must have the Previous Versions client installed
• Clients must use the share path to an object
to show the Previous Versions tab
• Shadows Copies do not replace regular backups
11
Restoring Shadow Copies
If…
Then…
No previous
versions
The file was not
modified after the
last save
Restoring a folder
The current version
is deleted
Restoring a file
File permissions are
not changed
Properties dialog
box does not
include a Previous
Versions tab
Shadow copies might
not be enabled
Copying a file
File permissions are
set to default

14
What Is a Failover Cluster?
A failover cluster is a group of independent computers that work
together to increase the availability of applications and services
Failover clusters include:
• A new validation feature to ensure that the system, storage, and
network configuration is suitable for a cluster
• Improved cluster setup
• Simplified configuration interface
• Improved stability and security, which increases availability
• Improved cluster communication with storage, which improves
the performance of a SAN or DAS
• Configuration options that eliminate the need for the quorum
as a single point of failure
• Improvements to the software infrastructure, networking and
security, which increase reliability and availability
15
Hardware Requirements for a Failover Cluster
Servers
Network adapters
and cable
Device controllers or
appropriate adapters
Storage
