I've noticed the following "bug" on a DFS volume with shadow copies:

Pretend you have the following folders/files under shadow copy versioning, going back two weeks.

MyDirectory
+ MyFile - Modified Date 8/1/2009

The current date: 8/30/2009

You have another version of MyFile stored elsewhere, with a modified date of 7/1/2009.

Copy your other version of MyFile into MyDirectory, overwriting the newest version. I expected that you could roll back to the version that was there when it last imaged, say on the prior day and recover your 8/1 version. Not the case. Now, when you go to look at previous versions for the past two weeks, the versioning of that file will be entirely lost, and you'll be stuck with your older 7/1 version. Suckage.

Questions:
(1) Is this intentional, and if so, what's the rationale? I assume that DFS picks up on the versioning based on the current file, and that's what's wiping out prior versions, but it seems like a fairly stupid/naive way of handling versioning to me.
(2) Is there a way to backtrack out of this, without resorting to restoration from other backup mediums?

Thanks!

I've tried a number of UPS units for numerous small business installations, as well as my own home systems and have yet to find a reliable brand. Some units last for years, other units of the same make/model end up burning out in 2 months. Not looking for the high-end here, but what brands/models have others found that work well consistently for small scale applications?

(Small scale being 1-3 servers, router and a couple of switches)
