Windows Server 2003 Compatibility with Former Backup Software
This article was previously published under Q327948
Windows Server 2003 contains a new backup infrastructure,
including new Application Programming Interfaces (APIs) for backup. Windows
Server 2003 also supports the backup APIs of Windows 2000. Because of the new
APIs in Windows Server 2003, backup programs can use the new Volume Shadow Copy
service (VSS). This service provides new backup functionality, including the
- It backs up files that are open for exclusive
- It provides backups of volumes that reflect the state of
those volumes at the instant the backup is started, even if the data changes
while the backup is in progress. This feature makes sure that all the data in
the backup is internally consistent and reflects the state of the volumes at a
single point in time.
- It notifies programs and services that a backup is about to
occur, which allows them to prepare for the backup by cleaning up on-disk
structures and by flushing caches and log files.
Because Windows Server 2003 still supports backup APIs from
Windows 2000, backup programs that are designed for Windows 2000 continue to
function as they did under previous versions of Windows. However, they may not
gain the benefits of the Volume Shadow Copy service.
