  1. 70-270, 70-290 MCSE/MCSA Guide to Installing and Managing Microsoft Windows XP Professional and Windows Server 2003 Chapter Fifteen Implementing and Managing Backups and Disaster Recovery

  2. Objectives • Back up and restore data • Describe operating system backup and recovery • Configure the Shadow Copies of Shared Folders feature Guide to MCSE 70-270, 70-290

  3. Objectives (continued) • Explain the purpose of the Automated System Recovery feature • Describe the Windows Server 2003 advanced startup options • Install and use the Recovery Console Guide to MCSE 70-270, 70-290

  4. Backing Up and Restoring Data • Must be prepared if disaster strikes • To assist in disaster recovery, Windows provides a number of tools: • Backup utility • Shadow Copies of Shared Volumes • Automated System Recovery (ASR) • Advanced startup options • Recovery console Guide to MCSE 70-270, 70-290

  5. Backing Up and Restoring Data (continued) • Backup utility: Used for restoring an OS or data in case of total hardware or storage media failure • Back up and restore files and folders • Schedule a backup • Back up Windows System State data • Restore all or a portion of the Active Directory database • Create an Automated System Recovery (ASR) backup Guide to MCSE 70-270, 70-290

  6. Backup and Restore Concepts • One primary duty of administrator is to ensure availability of data • Backups must be made regularly • Amount of data that must be backed up varies by organization • Biggest factor determining backup hardware and software needed is usually the amount of user and application data on network systems Guide to MCSE 70-270, 70-290

  7. Backup and Restore Concepts (continued) • Members of following local groups can back up any files and folders Windows Server 2003 or XP Professional system: • Administrators • Backup Operators • Server Operators • Otherwise, users must own file or have Read, Read & Execute, Modify, or Full Control permissions to it in order to back it up Guide to MCSE 70-270, 70-290

  8. Backup and Restore Concepts (continued) • Two main rights that affect being able to back up and restore files: • Back up files and directories • Restore files and directories • If granted in a GPO applied to the Domain Controller’s OU, apply to all domain systems • Can also apply locally or in a GPO • Archive attribute set on files to determine whether contents have changed since last backup Guide to MCSE 70-270, 70-290

  9. Backup and Restore Concepts (continued) Figure 15-2: The Back up files and directories Properties dialog box Guide to MCSE 70-270, 70-290

  10. Backup and Restore Concepts (continued) Figure 15-3: The Backup Job Information dialog box Guide to MCSE 70-270, 70-290

  11. Backup Types • Normal backup: Backs up all selected files and folders and clears the archive attribute on these files and folders • Most common and default backup type • Can be inefficient • Incremental backup: Backs up files that have changed since last normal or incremental backup • Clears archive attribute • Reduce size of backup jobs • More involved restore process Guide to MCSE 70-270, 70-290

  12. Backup Types (continued) Figure 15-4: Incremental backup and restore operations Guide to MCSE 70-270, 70-290

  13. Backup Types (continued) • Differential backup: Similar to incremental backup, but does not clear archive bit • Reduces backup size • Larger than incremental backup • Less involved restore process than incremental • Daily backup: Backs up selected files or folders created or changed on day the backup takes place • Copy backup: Same as normal backup, but does not clear archive bits Guide to MCSE 70-270, 70-290

  21. Operating System Backup and Recovery: Registry Fault Tolerance (continued) • Steps in a flush: • Alterations to a key appended to key’s transaction log file • Key file marked as being in transition • Key file updated with new data from memory • Key file marked as complete • Windows updates SYSTEM subkey and System.alt file separately from the flush Guide to MCSE 70-270, 70-290
