Provider name: 'Microsoft Software Shadow Copy provider 1.0' Provider type: System Provider ID: {b5946137-7b9f-4925-af80-51abd60b20d5} Version: 1.0.0.7 Provider name: 'HP StorageWorks MSA2000 Family VSS Provider' Provider type: Hardware Provider ID: {bd04cbf9-212c-4553-9ea5-c5bfb05ccc8f} Version: 2.6 Creating Shadow Copies VSS functionality includes creating, deleting, and managing shadow copies. However, to create a shadow copy, you must first use SMU to create a snap-pool, and then either convert an existing standard volume to a master volume (enable the volume for shadow copies) or to create a new master volume. If you try to take a snapshot of an ordinary volume that has not been converted into a master volume first, the VSS Hardware Provider will attempt to convert it to a master volume automatically, after allocating a backing store of approximately 20% of the size of the volume (but not less than 6GB). When the last snapshot is deleted, the volume will then be converted back to a normal volume to free up resources that might subsequently be needed to take snapshots of other volumes. Refer to your storage system's reference guide for more information. To create a shadow copy: 1. Use SMU to create a snap-pool and to either convert a standard volume to a master volume (enable the volume for shadow copies) or to create a new master volume.
