A) Yes, as a matter of fact there is. If you select faster backup performance in the performance settings menu, then the speed of the backup can be increased , so that only the changed information is transferred from the source to the backup target. But do remember that the IO performance on the volumes being backed up can be impacted. This is because Window Server Backup leaves a copy-on-write shadow copy behind on these volumes once the first backup is taken so that it can track changes made to the file system.
To Sum it all up:
|Type||System State Backup||Allcritical Backup|
|Incremental Target Usage||No||Yes|
|System State Recovery||Yes||Yes|
|Disaster Recovery from Setup DVD||No||Yes|
|Faster Backup Performance||No||Yes|
NOTE: This article applies only to Windows Server 2008. Windows Server Backup has many new exciting features in Windows Server 2008 R2 which we will be sharing in future blog posts.
