Lesson 1: Recovering Network Data with Shadow Copies• What Are Shadow Copies?• Considerations for Scheduling Shadow Copies• Demonstration: How to Configure Shadow Copies• Ways to Restore Data from a Volume Shadow Copy• Demonstration: How to Restore Data from a Shadow Copy

What Are Shadow Copies?Shadow copies:

•Allow access to previous versions of files

• Are based on tracking disk changes• Disk space is allocated on the same volume• When the space is full, older shadow copies are removed

•Are not a replacement for backups

•Are not suitable for recovering databases

Considerations for Scheduling Shadow Copies

• Default schedule is 7:00 A.M. and noon

• Create a shadow copy schedule based on:

• Volume of changes• Importance of changes• Storage limitations

Demonstration: How to Configure Shadow CopiesThis demonstration shows how to:• Enable shadow copies on C:• View settings for shadow copies

Ways to Restore Data from a Shadow Copy

• Previous versions are accessed in the properties of a file or folder

• Administrators can restore previous versions directly on the server

• Users can restore previous versions over the network

•Windows XP requires the Previous Versions client

• All users can:• Restore a file or folder• Copy a file or folder to an alternate location• Browse previous versions to select the correct version

Demonstration: How to Restore Data from a Shadow CopyThis demonstration shows how to:• Create a new file• Create a shadow copy• Modify the file• Restore a previous version

Lesson: Recovering Network Data and Servers with Windows Server Backup• What Is Windows Server Backup?• Types of Backup• Differences between versions of Windows Server Backup• Who Can Back up Data?• What Is System State Data?• Recovery Options

What Is Windows Server Backup?

• Windows Server Backup is a feature that allows you to back up and recover files, folders, or an entire server

• Most larger organizations use an alternative solution for backups

• Backups can be stored on:• A local disk• An external USB drive• A network share• DVD

• Backup jobs can be scheduled

Types of Backup

• Terminology is unique:• Full backups copy all files but store only changes• Incremental backups copy only changed disk blocks• Both provide the same result in different ways

• VSS full backups:• Clear the archive attribute• Truncate application log files

• VSS copy backups:• Do not clear the archive attribute• Do not truncate application log files

Differences between Versions of Windows Server Backup

Windows Server 2008 Windows Server 2008 R2

Back up only full volumes Back up full volumes or specific files and folders

Dedicated backup volumes are required

Backups can be stored on volumes shared with other data

Does not support scripting with PowerShell Supports scripting with PowerShell

Scheduled backups must be created on local storage

Scheduled backups can be stored on a network share

Who Can Back Up Data?

• User rights control the ability to:• Back up files and folders• Restore files and folders

• Groups able to back up and restore are:• Administrators• Server Operators• Backup Operators (domain controllers only)

What Is System State Data?

Component When is this component included in System State?

Registry AlwaysCOM+ Class Registration database AlwaysBoot files, including the system files AlwaysActive Directory Certificate Services database If it is a Certificate Services server

Active Directory Domain Services database If it is a domain controller

SYSVOL directory If it is a domain controllerCluster service information If it is within a clusterIIS Metadirectory If it is installedSystem files that are under Windows Resource Protection Always

Recovery OptionsRestore an entire server by starting up from the Windows Server 2008 installation DVD

Lab Scenario• Recently, a new file server was implemented for the

marketing department. Somehow in the planning process, no one considered how data on the server would be protected. You need to configure volume shadow copies on the server to simplify recovery of files. You also need to configure a scheduled backup for disaster recovery.

Lab Review• Why did you need to go to the properties of the share to

restore a deleted file from a shadow copy?• When you performed the second backup, why did the disk

space in use not increase on the destination drive?
