O.K., that makes sense. I am starting to understand this now.

I didn't describe very well what I am doing with E:\ and M:\. It is not as complicated as I made it sound.

My files are on my C:\ and my D:\ drives. I back up the C:\ data to a directory (Disk 1) on the E:\ drive; I back up the D:\ data to a second directory on the E:\ Drive (Disk 2).

Then I repeat the process, backing up to Drive M:\. This suggests to me that E:\ and M:\ should be more or less identical. They aren't. I'll keep an eye on them, examine them with the Restore module, and see if I can find out why. Maybe it's something simple like I didn't turn off compression on the M:\ drive or something.

Thank you, Christian, for the clarification. You are pretty good at that!
