XP Restore Point. How does it do this?

[ssoni223]

I did a new fresh install of XP.
All my apps installed.
All settings done.

Added a restore point while I have a pristine OS running.

I expected this to take a big chunk of space and disk writing
As if it does a large copy...
However, I clicked "ok" and it was done almost immediately.

Is this right?
Is this reliable?

Yep it's right and reliable and let me be the first to congratulate you on the wise decision of using System Restore.

It's a very fast process and usually completes in about the time it takes to lift your finger off the mouse button.
Restore Points are stored in your System Volume Information folder. This folder by default does not allow anyone (even admins) access so depending on how you are viewing drive space you may not notice this space has been consumed.

You can add permissions for yourself to this folder if you want to go take a look. Only look though ... don't touch

I mirrored the HD onto a seperate physical drive (to be safe)
However, if this OS gets corrupt, I will try the rollback.
If that's not enuf, then I will use the backup HD
