 Implementing Fault Tolerance by Using RAID RAID Implementations Mirrored Volumes RAID-5 Volumes Implementing Fault-Tolerant Volumes Recovering a Failed Mirrored Volume Recovering a Failed RAID-5 Volume

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

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

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

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
