The backup functionality in Windows Server 2008 and 2008 R2 is a new backup system called Windows Server
Backup that uses drive imaging technology. This represents a radically different approach to Disaster Recovery
and a departure from the file-based method in Windows 2003 and prior.
BackupAssist allows you to take advantage of Microsoft’s extensive R&D investment in drive imaging technology,
while also addressing some of the drawbacks. The net result is a reliable, monitored and effective disaster
protection system that otherwise would have cost many times more on Windows Server 2003.
