We use RAID levels such as RAID 0 and RAID 10, both of which stripe data across multiple disks. Striping works by dividing data to be written to disk into chunks and spreading the chunks over the separate disks in the RAID array.

Recovering from a Disaster in an Exchange Server 2007 Environment : Recovering from a Site Failure & Recovering from a Disk Failure

For environments where SLAs offer very little time to bring up a recovery location, administrators should strongly consider implementing Cluster Continuous Replication, a new feature of Exchange 2007.

Preventive Maintenance and Data Recovery

Restoring a Complete PC Backup involves erasing your hard disk and replacing all your data with the data in the backup. This means any data on your hard disk created or modified since your last backup will be sucked into oblivion, so you'll likely only want to use this feature if your hard disk crashes.
