Amazon Elastic Compute Cloud (Amazon EC2) now supports Microsoft Volume Shadow Copy Services (VSS) enabled EBS snapshots for Windows Server AMIs. VSS is a Microsoft technology that allows application data to be backed up while applications are still running, by coordinating between user applications that update data on disk and those that back up applications. With this launch, you can now take VSS-enabled EBS snapshots of your running Windows instances without the need to create custom scripts, or shutting down the instances.
