Over on the Configuration Manager Team blog Jeff Gilbert comes through again with another awesome post on how Configuration Manager Backup uses the Volume Shadow Copy service to work it’s magic. If you’ve ever wondered what was going on under the covers or curious how you can customize how backups are done then this is a great place to start. I have his intro and a link below:
The Volume Shadow Copy Service (VSS) is a Windows service that made its debut with Windows XP and Windows Server 2003. This service provides the ability to create a point in time image (shadow copy) of one or more volumes. These shadow copies can then be used to perform backup operations. Shadow copies are created very quickly in general because instead of backing up an entire volume file by file, VSS only needs to track changes to existing files. By tracking disk changes at the volume level, VSS is able to present a static snapshot of changed data to a backup process and then copy a point-in-time snapshot of those files to a backup destination even while the actual files are being written to.
