Does the Volume Shadow Copy Service that comes with Windows Server 2003 only start and come in to the running state in service control when it is actually taking a snapshot?

I have been googling and reading articles but they tend to all just tell me the basics of how to use it or the architecture of it, and I've been unable to find the answer to my question, so I was hoping that someone could share their wisdom on this with me.

Is has been my observation that both services "MS Software Shadow Copy Provider" and "Volume Shadow Copy" both come in the Manual Startup Type by default in services. This would seem to support that they do not run all the time to watch things, but only when taking a snapshot?

Can anyone shed more light on this?

There is a list of defaults in the services' help file.

oh thanks, hadn't seen that before...

Doesn't quite answer the question, I take it then the services only run when a snapshot is actually being taken them, not all the time.

If this is the case, then I can't just monitor the service is running to know if VSS is working...

So how then can I check programmatically that Volume Shadow Copies are actually working?

Scroll down until you see an inside scroll bar, then use that one until you see the heading

How to check snapshot consistency.

That might be what you want.
