 a few questions on the shadow copy feature:

1) will shadow copies be made of files that are:
a) compressed via builtin NTFS compression feature? (yes/no/depends)
b) encrypted via EFS? (yes/no/depends)

these next questions assume answers to number 1 above are 'yes' or
'depends'.

2) when *restoring* files using Previous Versions client (not saving to
*new* location):
a) will compressed files remain compressed?
a1) if original source folder is still compressed?
a2) if original source folder was compressed when shadow copy was
made but now is not?
a3) if original source folder was never compressed (only the file
was compressed when shadow copy was taken)?

b) will encrypted files remain encrypted?

c) will the original NTFS permissions assigned at the time of the shadow
copy remain?

3) I am assuming that when *copying* or saving a previous version to a new
location that the same rules for compression, encryption, and NTFS
permissions apply as would during a normal copy operation. (yes/no)?

any input on this would be greatly appreciated. Thanks.

 Great questions, but given that they (mostly) have nothing to do
with security, and are NTFS or VSS specific, perhaps this would
be better addressed is asked in
microsoft.public.windows.file_system

Sounds like someone's studying for something. Perhaps someone should be
trying these things out for one's self.

Agreed and agreed, Paul.
Most all would be fairly quickly discoverable with some tests.

Paul & Roger, get off your high horses. Ever heard of multi-tasking? I hate
responses like that. I use all resources available to get answers. Just
because I am asking a question that can be easily figured out by testing
does NOT mean I shouldn't ask it or that it doesn't deserve an answer. I can
be in the middle of testing several things to learn and get answers, as well
as reading books and tutorials, as well as posting questions to newsgroups.
I get a LOT more done in a shorter amount of time that way.

In actuallity it is called 'being smart' and using all available resources
to solve several problems simultanously.

Just because I ask a question that is easily discoverable by testing does
NOT mean that:
- I don't spend enough time 'experimenting' and 'doing'.
- I don't understand the importance of actual hands-on learning and
experience.
- I think I can get by on book knowledge alone and I am trying to do so.

your responses (excluding the suggestion to post in a more appropriate
group - that at least is good advice) are more fitting for one of the many
*unfriendly* linux newsgroups out there. Not to knock the linux community,
but they *are* known for being very n00bie intolerant and have the 'figure
it out yourself dimwit' attitude. Not all of them, but the majority.

hopefully you both will find this at least a little enlighting and realize
that everyone out there that asks questions like this are *not* just trying
to cut corners or skip out on the *most* important thing of all: hands-on
experience.

obviously, I'm offended.

have a nice weekend! :)
