Module Overview Backing Up Data Configuring Shadow Copies Providing Server and Service Availability

Lesson 1: Backing Up Data Windows Server Backup Overview New Windows Server Backup Features Who Can Back Up Data? What Is System State Data? Optimizing Backup Performance Specifying a Backup Time How Is Data Restored? Demonstration: Installing and Configuring Windows Server Backup

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

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 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? RegistryAlways COM+ Class Registration databaseAlways Boot files, including the system filesAlways Active Directory Certificate Services database If it is a Certificate Services server Active Directory Domain Services database If it is a domain controller SYSVOL directoryOnly if it is a domain controller Cluster service informationIf it is within a cluster IIS configuration filesIf it is installed System files that are under Windows Resource Protection Always

Optimizing Backup Performance

Specifying a Backup Time Run Backup daily or more often 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 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?

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: 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

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

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?
