%1 %2 [/Provider=ProviderNameOrID] /For=ForVolumeSpec       /On=OnVolumeSpec [/MaxSize=MaxSizeSpec]      - Resizes the maximum size for a shadow copy storage association between       ForVolumeSpec and OnVolumeSpec.  Resizing the storage association may       cause shadow copies to disappear.  If MaxSizeSpec is not specified,       there is no limit to the amount of space it may use.  As certain shadow       copies are deleted, the shadow copy storage space will then shrink.        MaxSizeSpec must be 1MB or greater and accepts the following suffixes:       KB, MB, GB, TB, PB and EB.  Also, B, K, M, G, T, P, and E are acceptable       suffixes.  If a suffix is not supplied, MaxSizeSpec is in       bytes.  If the provider is the supplied Microsoft provider,      MaxSizeSpec must be 100MB or greater.      - The Provider ID can be obtained by using the List Providers command.      When entering a Provider ID, it must be in the following format:         {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}       where the X's are hexadecimal characters.
