  1. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network, EnhancedChapter 14: Problem Recovery

  2. Objectives • Back up and restore files • Recover corrupted systems • Perform remote management • Image client computers and servers 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  3. File Backup and Recovery • File backup and recovery are an essential part of network maintenance • When data is backed up, you can recover an uncorrupt version • Effective backup and recovery solution includes • Backup (ntbackup.exe) • Volume shadow copy 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  4. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

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

  6. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  7. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  8. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  9. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  10. File Backup Strategies (continued) 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  11. Activity 14-1: Performing a Backup • The purpose of this activity is to perform a full and an incremental backup 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  12. Activity 14-2: Performing a Restore • The purpose of this activity is to Restore a file from backup 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  13. System State Backup • Backup utility is can backing up system state data: • Registry • COM+ Class Registration database • Boot files • System files • Use Directory Services Restore Mode to restore system state 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  14. Automated System Recovery • Backup can perform an automated system recovery (ASR) backup • Is a last resort to recover systems that you have not been able to recover using other more common tools • When an ASR backup is performed, all of the OS is backed up 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  15. Volume Shadow Copy • Volume shadow copy makes copies of files, including open files • Allows users to restore previous versions of files without administrator involvement • A volume shadow copy sets aside disk space to store changes to files that have occurred since the volume shadow copy was performed • Only files that have changed take up additional disk space 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  16. Activity 14-3: Configuring and Using Volume Shadow Copy • The purpose of this activity is to configure volume shadow copy to allow users to restore files from the previous day 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  17. Recovery Tools • Recovery tools • Device driver rollback • Safe mode • Last known good configuration • Recovery Console 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  18. Device Driver Rollback • Device driver rollback reverts to previous version of a device driver at any time after an update • Available through Device Manager 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  19. Device Driver Rollback (continued) 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  20. Safe Mode • Used when a server becomes misconfigured or corrupt • Loads a minimal set of drivers • Can repair the system by updating drivers, reinstalling software, or removing corrupt software 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  21. Activity 14-4: Accessing Safe Mode • The purpose of this activity is to enter into safe mode. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  22. Last Known Good Configuration • Last known good configuration is useful if no user has logged on since a change was made • If a new device driver is installed and the system encounters severe errors, then last known good configuration can restore registry to before the installation • Does not delete the files associated with the driver, but does prevent them from being loaded during startup 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  23. Activity 14-5: Using Last Known Good Configuration • The purpose of this activity is to use last known good configuration to restore service and driver settings. 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  24. Recovery Console • Recovery Console allows you to access system settings and files when Windows cannot be started • Useful when safe mode and last known good configuration are not effective • Recovery Console can perform disk management • Can re-create the master boot record on the hard drive and the boot sector on the active partition 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  25. Activity 14-6: Installing and Using Recovery Console • The purpose of this activity is to install and use Recovery Console 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  26. Remote Management • Terminal Services lets users connect to a remote computer and run applications remotely • Users must have client software installed on their workstations to connect to a terminal server • Client software on the workstations creates a desktop environment based on screen draw commands • Much more efficient for remote access than a VPN 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  27. Remote Desktop for Administration • Remote Desktop for Administration allows up to two users at a time to administer a server remotely using Terminal Services • All server features can be accessed just as if you were sitting at the server console 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  28. Remote Desktop for Administration (continued) 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  29. Remote Desktop for Administration (continued) 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  30. Activity 14-7: Using Remote Desktop for Administration • The purpose of this activity is to use Remote Desktop for Administration to remotely connect to a server 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  31. Remote Assistance • Remote Assistance is for users to ask experts for help • In a corporate setting, the experts are normally the help desk or application support specialists 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  32. Activity 14-8: Using Remote Assistance • The purpose of this activity is to use Remote Assistance to request help 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  33. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  34. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  35. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  36. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  37. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  38. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  39. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  40. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  41. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  42. 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 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  43. Summary • Full backups turn off the archive attribute • Incremental backups back up daily changes and turn off the archive attribute • Differential backups back up all files that have changed since last full backup and do not affect the archive attribute of files that are backed up • A system state backup backs up the system state data • ASR backup takes a copy of the OS and creates a floppy disk for the disaster recovery process 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  44. Summary (continued) • Volume shadow copy takes a snapshot of files • Device driver rollback restores previous version of a device driver • Safe mode starts the OS with limited services • Last known good configuration restores the part of the registry responsible for service and driver configuration 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network

  45. Summary (continued) • Recovery Console allows you to access files and systems settings when Windows cannot be started • Windows Server 2003 includes Remote Desktop for Administration • RIS (Remote Installation Services) images and installs Windows Server 2003, Windows XP, and Windows 2000 70-293: MCSE Guide to Planning a Microsoft Windows Server 2003 Network
