shadow drive recovery

[Guest Signal_Redman]

I'm new to WIN.VISTA.

I was setting up auto back-up to a DVD-R disk.

I accidentally ran a back-up to my D: drive (7GB) on my system and it filled

up the D: with a back-up. I want to remove the back-up from the shadow drive

but it says if I delete information from the shadow drive I may not be able

to restore my systems information if I later need to do a recovery action.

 

My question, Is it okay to delete the back-up files and will my previous

show files remain in tact.
