1. 1 Week #10Business Continuity Backing Up Data Configuring Shadow Copies Providing Server and Service Availability

2. 2 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

3. 3 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

4. 4 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

5. 5 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

6. 6 Optimizing Backup Performance

7. 7 Specifying a Backup Time Run Backup daily or more often Back up the entire server or specific volumes only

8. 8 How Is Data Restored?

9. 9 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

10. 10 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

11. 11 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

12. 12 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

13. 13 Network Load Balancing Manager Overview Accept? No Yes No Client Client Request Network Load Balancing Host Dedicated IP: 10.1.1.2 Virtual IP: 10.1.1.1 Network Load Balancing Host Dedicated IP: 10.1.1.3 Virtual IP: 10.1.1.1 Network Load Balancing Host Dedicated IP: 10.1.1.4 Virtual IP: 10.1.1.1 Network Load Balancing Host Dedicated IP: 10.1.1.5 Virtual IP: 10.1.1.1

14. 14 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

15. 15 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

16. 16 Hardware Requirements for a Failover Cluster Servers Network adapters and cable Device controllers or appropriate adapters Storage
