2 Overview Introduction to Disaster Protection Configuring an Uninterruptible Power Supply Implementing Fault Tolerance by Using RAID Backing Up and Restoring Data Using Disaster Recovery Tools

3 Introduction to Disaster Protection Fault Tolerance Disaster Recovery Disaster Protection

4 Configuring an Uninterruptible Power Supply Power Options Properties Power SchemesAdvancedHibernateAPM UPS Status Details Current power source: Estimated UPS runtime: Estimated UPS capacity: Battery condition: Current power source: Estimated UPS runtime: Estimated UPS capacity: Battery condition: Manufacturer:American Power Conversion Model:Back-UPS Pro To commit the new settings, choose OK or Apply. Uninterruptible Power Supply Configure…Select… About… OKCancelApply UPS Configuration Enable all notifications. Seconds between power failure and first notification: Seconds between subsequent power failure notifications: Critical alarm A critical alarm occurs when the UPS battery is almost exhausted or, optionally, after a specified time on battery power. Minutes on battery before critical alarm: When the alarm occurs run this program: 2 Configure… Next, instruct the computer to: Finally, turn off the UPS. Shutdown OKCancel

5 Implementing Fault Tolerance by Using RAID Implementing Fault Tolerance by Using RAID RAID Implementations Mirrored Volumes RAID-5 Volumes Implementing Fault-Tolerant Volumes

6 RAID Implementations Software Implementation (Supported by Windows 2000 Server) RAID 0: Striped Volumes RAID 1: Mirrored volumes RAID 5: Striped volumes with parity Hardware Implementation Disk controller interface handles the creation and regeneration of redundant information RAID level dependent on hardware manufacturer

7 Mirrored Volumes Mirrored volumes use Ftdisk.sys to simultaneously write data to two volumes on two physical disks. Mirrored Volume Disk 0Disk 1 C: C:Ftdisk.sysFtdisk.sys Fault Tolerance Driver Fault Tolerance Driver Data

9 Backing Up and Restoring Data Overview of Data Backup and Restoration Backup Types Example Backup Schedules Configuring File and Folder Backup Backing Up System State Data Scheduling a Backup Restoring Files and Folders

10 Overview of Data Backup and Restoration The Goal of Backing Up Data Is to Restore Data If It Is Lost Permissions and User Rights Are Required to Back Up and Restore Data Data BackupBackup Data Corruption RestoreRestore Data

11 Backup Types TypeType Normal Backs up Selected files and folders Clears marker Yes Copy Selected files and folders No Differential Selected files and folders that changed since the last backup No Incremental Selected files and folders that changed since the last backup Yes Daily Selected files and folders that changed during the day No

13 Configuring File and Folder Backup When you create a backup job, you specify: Drives, Folders, or Files to Back Up Backup Destination Path and File Name, or a Tape to Use Backup Options Description of the Backup Job Whether the Media Contains Existing Backup Jobs Advanced Backup Options

14 Backing Up System State Data Registry CS* Class Registration Database System Startup Files Certificate Services Database DC ** ComponentComponent Server *** Active Directory Sysvol Folder ProfessionalProfessional * CSComponent Services ** DCA domain controller running Windows 2000 Server *** Server A computer running Windows 2000 Server that is also a certificate server * CSComponent Services ** DCA domain controller running Windows 2000 Server *** Server A computer running Windows 2000 Server that is also a certificate server

15 Scheduling a Backup Specify a User Name and Account with the Appropriate Permissions Specify a Job Name Specify the Date, Time, and Frequency

16 Restoring Files and Folders Folders or Files to Restore A Restore Location Restore Options

17 Using Disaster Recovery Tools Using Disaster Recovery Tools Starting a Computer by Using Advanced Startup Options Recovering a Computer by Using the Recovery Console Recovering a Computer by Using Disk Image Process

18 Starting a Computer by Using Advanced Startup Options Operating System Selection Safe Mode Safe Mode with Networking Safe Mode with Command Prompt Enable Boot Logging Last Known Good Configuration Directory Services Restore Mode Debugging Mode Loads basic devices and drivers Loads safe mode options and networking services and drivers Loads safe mode options but starts a command prompt instead of the graphical user interface Logs the loading and initialization of drivers and services F8 Enable VGA Mode Loads the basic VGA driver Uses the last known good configuration to start the computer Allows Active Directory restoration on domain controllers Enables debugging

19 Recovering a Computer by Using the Recovery Console Use the Recovery Console to: Start and stop services. Read and write data on a local hard drive. Format hard disks and display hidden system files.
