Those restore systems are not from Microsoft so to nail this one I'd share the make and model of the machine.
Running XP Home with SP2.
What is C:\ My Backup? I've only noticed it's presence since performing a
Destructive Restoratoin about a month ago. Can some one tell me where it came
from or if it is just part of the OS which I never before noticed? It's quite
large, about 9GB. But I don't particularly mind as several times searching for
a missing file or folder, I would find the only copy, or non-corrupt copy in C:\
My Backup. And it's size is not a problem as I have plenty of storage space to
spare. The only info I could find on it was a tech forum post asking what it
was, which went unanswered. And a another giving instructions how to remove it.
