clarification for VSS UseMicrosoftProvider setting

[Guest Hong]

It is documented the DWORD entry "UseMicrosoftProvider=1" at the hive

 

HKLM\SYSTEM\CurrentControlSet\Control\BackupRestore\

 

will force Windows 2003 SP1's NTBackup to use the built-in Microsoft VSS

Software provider, a useful exclusion test to see if third-party VSS Software

provider is at fault

 

1. Does this also apply for XP SP2 platform?

 

2. Is the default "UseMicrosoftProvider=0" when there is no presence of this

value, then a third-party VSS Software provider is used if present?

 

3. If there're more than one third-party VSS Software providers, how to

select a specific non-Microsoft third-party VSS Software provider to be the

default?

 

4. Can VSSTRACE reveal which one is in use?
