Can I use System Restore Points WITHOUT Shadow Copies? Relationship?

I am uncertain what the differences are between System Restore Points and Shadow Copies.

Actually I need only System Restore Points.

1.) Can I use SRP without (!) Shadow Copies?

2.) When Shadow copies always necessary: Why are SRP invented?
Why not using Shadow Copies only?

3.) Assume I delete a file WITHOUT moving it to the recycle bin but by immediate full true delete.
Will there a copy still persist in Shadow Copy?
Wouldn't that be a security hole?

4.) As far as I understand Shadow Copies are permanently automatically created by Win 7.
Can I somehow tell Win 7 only to create a Shadow Copy when I create a System restore Point?

5.) Assume I reserve a space of 5 GB for System Restore Points: is this the space which is used for Shadow Copies (too)?

Hi Peter,
System Restore is dependent on the VSS service to be running to complete ITS process, and will return a failure window if not.

have a read of this Wiki artical.

Volume Shadow Copies or VSS is a low level technology that a number of Windows features rely on. The ability to maintain copies of user files is just the most visible of them. System Restore, most backup programs, and other features rely on it as well.
