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

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

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
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
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
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

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
