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.

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
