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

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

How Is Data Restored?

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
