4 9/19/2015 Operating System 4 How System Image Backups Work System Image backups make a block-by-block backup of your system volume to a.vhd file, which must be stored on local storage, such as a second hard disk. the media automatically perform only an incremental backup. In other words, only the portions of the hard disk that have changed are copied to the existing System Image backup. Unlike file backups, only a single version of the System Image backup is kept multiple versions are not stored. The Backup And Restore tool does not provide a graphical tool for scheduling automatic System Image backups. Instead, you should rely on automatic file backups and manually create a System Image backup only after you have made significant changes to a computer s configuration.

5 9/19/2015 Operating System 5 Continue How to Start a System Image Backup from the Command Line The simplest way to initiate a System Image backup is to follow the prompts in the Backup And Restore Center. For example, to initiate a System Image backup of the C drive to the L drive, you can run the following command line from an elevated command prompt. Wbadmin start backup backuptarget:l: -include:c: -quiet 1

6 9/19/2015 Operating System 6 System Image Backup Structure System Image backups use a similar folder structure to file backups. When you create a System Image backup, Windows creates a WindowsImageBackup folder in the root of the backup media. Within that folder, it creates a folder with the current computer s name. It then creates a Catalog folder containing the Global Catalog and Backup Global Catalog files and a Backup <year>-<month>-<date> <time> folder containing the disk image file. 2,3

7 9/19/2015 Operating System 7 How to Manage Backup Using Group Policy Settings Group Policy is the central component of the Change and Configuration Management features of the Microsoft Group Policy specifies settings for groups of users and of computers, including registry-based policy settings, security settings software installation Scripts folder redirection 4

8 9/19/2015 Operating System 8 Continue... You can use Group Policy to manage Windows Backup options in an enterprise environment. The policy settings for Windows Backup are both user and computer settings. The user- specific settings are client-only settings and are found in the following location: User Configuration\Policies\Administrative Templates\Windows Components\Backup\Client

11 9/19/2015 Operating System 11 How Volume Shadow Copy Works To provide backups for files that are in use, Windows 7 uses the Volume Shadow Copy service, which was first introduced with Windows XP. Volume Shadow Copy mitigates file access between applications and the backup process. In other words, if a backup tool needs to access a file currently in use, Volume Shadow Copy creates a shadow copy of that file and then provides the backup process access to the shadow copy.

13 9/19/2015 Operating System 13 Continue Volume Shadow Copy works with any application. Some applications, however, can communicate directly with the Volume Shadow Copy service to ensure that backed-up files are consistent. If an application keeps several files in use at the same time, they might become inconsistent if two files must be synchronized and one of those files is updated after another is backed up in an earlier state.

14 9/19/2015 Operating System 14 Continue To provide backup access to a file that is open and being updated, Volume Shadow Copy needs to be able to make two versions of the file accessible: one that is currently in use by the application and a second that is a snapshot of the file when backup first requested access to a volume shadow copy volume Shadow Copy handles this transparently by storing copies of changed files in Volume Shadow Copy storage. Volume Shadow Copy stores a copy of the original state of any modified portion of a file, which allows the original file to be updated without interrupting the backup process.

15 9/19/2015 Operating System 15 MSConfig Microsoft software utility first introduced with Windows 98 and included with all later versions of Windows that enables users to configure how their computer starts and what programs or services automatically load each time the computer starts. Users running these versions of Windows can open msconfig by following the below steps. Click the Start orb in the Start Search Type msconfig and press enter, once done you should see the System Configuration Utility window

If you've changed any of the settings in the Boot tab or disabled any programs or services from starting up the Selective startup will be selected. If Selective startup is enabled and startup programs or services have been disabled, a notice will appear when the computer first starts letting you know that Selective startup is enabled. 5
