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
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
New Windows Server Backup Features
Simplified restoration Simplified recovery of your operating system
Ability to recover applications
Improved scheduling
Offsite removal of backups for disaster protection
Remote administration
Automatic disk usage management Extensive command-line support Support for DVD media
Faster backup technology
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 thatseparate the backup and restore User Rights Assignments
• Limit the number of users that belong to the default groups with backup/restore rights
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
Specifying a Backup Time
Run Backup daily or more oftenRun Backup daily or more often
Back up the entire server or specific volumes only
Back up the entire server or specific volumes only
How Is Data Restored?
Demonstration: Installing and Configuring Windows Server Backup
In this demonstration, you will learn how to install and configure Windows Server Backup
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
• Demonstration: 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
• Allocated storage limits versions
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
• Shadows Copies do not replace regular backups
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
Demonstration: Restoring Shadow Copies
In this demonstration, you will see how to restore a shadow copy
Lesson 3: Providing Server and Service Availability

Creating a Network Load Balancing Cluster
To configure Network Load Balancing, you must configure three types of host parameters:
• Host Parameters
• Cluster Parameters
• Port Rules
Optional
Network Load Balancing Hosts
Router/Gateway
Front-end LAN
Back-end LAN
Server cluster
Node 1 Node 2
Shared storage

In this demonstration, you will see how to configure a Network Load Balancing cluster
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
Hardware Requirements for a Failover Cluster
Servers Network adapters and cable
Device controllers or appropriate adapters
Storage

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?
