Backup

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



Extensive command-line support



Support for DVD media

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

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 Always Resource Protection

Optimizing Backup Performance

Specifying a Backup Time Back up the entire server or specific volumes only

Run Backup daily or more often

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 Shadow copies might does not include a not be enabled Previous Versions tab 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 • Network Load Balancing Manager Overview • Demonstration: Installing Network Load Balancing • Creating a Network Load Balancing Cluster • Demonstration: Configuring a Network Load Balancing

Cluster

• What Is a Failover Cluster? • Failover Cluster Hardware Requirements

Network Load Balancing Manager Overview Client Request

Network Load Balancing Host Dedicated IP: 10.1.1.2 Virtual IP: 10.1.1.1

Accept? No

Network Load Balancing Host Dedicated IP: 10.1.1.3 Virtual IP: 10.1.1.1

Accept? No

Network Load Balancing Host Dedicated IP: 10.1.1.4 Virtual IP: 10.1.1.1

Accept? Yes

Client

Network Load Balancing Host Dedicated IP: 10.1.1.5 Virtual IP: 10.1.1.1

Accept? No

Demonstration: Installing Network Load Balancing In this demonstration, you will see how to install Network Load Balancing

Creating a Network Load Balancing Cluster To configure Network Load Balancing, you must configure three types of host parameters:

Router/ Gateway Front-end LAN

• Host Parameters

Network Load Balancing Hosts

• Cluster Parameters • Port Rules

Back-end LAN

Shared storage

Optiona l Node 1

Node 2

Server cluster

Demonstration: Configuring a Network Load Balancing Cluster 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 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?
