Windows Server Backup Overview
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
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

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

Lesson 2: Configuring Shadow Copies
•
What Are Shadow Copies?
•
Shadow Copy Scheduling
•
Demonstration: Configuring Shadow Copies
•
Managing Shadow Copies from a Client Perspective
•
Restoring Shadow Copies
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
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
Demonstration: Configuring Shadow Copies
In this demonstration, you will see how to configure
shadow copies
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
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

In this demonstration, you will see how to restore a
shadow copy

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
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

Lab Review
•
What default groups in Windows Server 2008 have the
right to backup and restore data?
•
Where Shadow Copies are enabled, is there a limitation on
the number of shadow copies per volume that Windows
Server 2008 keeps?
•
When a user chooses to make a copy of a previous
version, what happens to the permissions for the new
object? Does it retain the security setting or revert to the
default setting?
