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

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?
