4. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network4 The Backup Utility When backups are performed, they can be stored on tape or in a file Tape is more common Backup to file is used with nontraditional media, such as a floppy disk, hard drive, or CD-R The entire backup is stored inside a single file, making it easy to copy and move

5. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network5 Backing Up Application Data Backup utility is part of Windows Server 2003 Third-party backup solutions are available Easier to use Have enhanced features

6. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network6 File Backup Strategies Three backup strategies for daily file system backups: Full Incremental Differential Each time a file is modified, the OS turns on the archive attribute of that file Each backup strategy uses and affects the archive attribute of files differently

7. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network7 File Backup Strategies (continued) Full backup Backs up all selected files each time a backup is performed Simplest type of backup to implement Use the backup tape from the previous day to restore Archive attribute on each file is turned off Primary problem is the large amount of time

8. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network8 File Backup Strategies (continued) Incremental backup: Only the files that have changed since the previous backup Less than 10% the size of a full backup Always used in combination with full backups Only backs up files with archive attribute turned on

9. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network9 File Backup Strategies (continued) Differential backup: Files that have changed since the previous full backup Always used in a cycle that begins with a full backup Does not turn off the archive attribute on files that are backed up Is a compromise between full daily and incremental Differential is much faster to perform than a full backup Not quite as fast as an incremental backup

33. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network33 Imaging Client Computers and Servers Imaging installs an entire OS in one step Software takes a copy of an entire hard drive or partition and stores it as a file Contents of the file are copied onto a client computer Time required is much less than for full application and OS installation

34. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network34 Imaging Client Computers and Servers (continued) Windows Server 2003 includes a solution for imaging called RIS (Remote Installation Services) A number of third-party imaging solutions, such as Norton Ghost, are also available

35. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network35 Remote Installation Services RIS can install Windows Server 2003, Windows XP, and Windows 2000 Both RIPrep images and flat images are supported RIPrep image is a fully installed OS and applications Can be installed in 10 minutes or less depending on its size

36. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network36 Remote Installation Services (continued) To create a RIPrep image: Install OS Install and configure applications Run RIPrep.exe: takes an image of the local computer and copies to the RIS server RIS server stores the image on its local hard drive A flat image is a scripted installation of the OS Requires 45 to 90 minutes Applications are not automatically installed

37. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network37 RIS Server Requirements Can install RIS server on any hardware that meets the requirements for Windows Server 2003, except: RIS server cannot be multihomed RIS server must have a 4-GB volume, which is not the system or boot volume The volume holding RIS must be an NTFS volume The recommended speed for the network in RIS servers is at least 100 Mbps

38. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network38 RIS Client Requirements RIS client must: Meet minimum hardware requirements for OS Have a Pre-Boot eXecution Environment (PXE) boot ROM version 1.00 or greater to connect to the RIS server

39. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network39 RIS Network Services Services required by RIS are DHCP, DNS, and Active Directory DHCP provides an IP address and configuration information to the RIS client DNS locates a domain controller and authenticates to Active Directory Active Directory identifies prestaged computers, creates computer accounts, and authenticates users

40. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network40 The RIS Imaging Process After RIS client gets a reply to its service request, it downloads a bootstrap program from the TFTP (Trivial FTP) service on the RIS server startrom.com is downloaded by default Displays a message to press F12 to perform a network installation If F12 is not pressed after three seconds, the boot process continues to the next device such as a hard drive

41. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network41 The RIS Imaging Process (continued) If the user presses F12, then the Client Installation Wizard is downloaded via TFTP from the RIS server Client Installation Wizard gets user to authenticate If the account has not been prestaged, the user performing the imaging needs permission to create computer accounts in Active Directory User selects an image to install

42. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network42 Third-party Imaging Utilities Using third-party imaging software is similar to using RIPrep images with RIS OS is installed Applications are installed Sysprep is run to prepare the computers for imaging Third-party imaging software is used
