I keep my data on a partition other than the system partition.
The W7 ProgramData resides on the system partition.
I use partition imaging technology to restore prior versions of my system partition at times.
I image my system partition (C:) on 12/31/2012
On 8/30/2013, I restore my system partition using the 12/31/2012 image
My Data partition (D:) remains unaffected
The W7 ProgramData folder on C: is now as it was on 12/31/2012
Doing so restores ProgramData that MAY have been relevant to my actual data, so I am concerned that this could present a problem.
For example: it appears to me that some programmers store ProgramData that is specific to actual data on my Data partition (D:). e.g. Connected Backup creates an Email Backup Optimization folder that I believe contains metadata concerning my data. Upon restoring my system partition, this metadata is old and now inaccurate/incomplete with respect to my actual data. So it seems to me that such data-related-metadata belongs on my data partition...?
Would appreciate some guru thoughts on this matter re: Pros & Cons of relocating W7 ProgramData folder
