I have set up a DFS pair of servers that are on either ends of my organization's WAN. The synched folder hierarchy has 9M+ files (tiny ones).

To seed the remote end, the source files were GZipped and moved across the WAN.

Somehow, this caused a 1-hour shift of the timestamps in the forward direction of the remote copies, BUT only for files with calendar dates that fall out of Daylight Saving Time.

What this amounts to is a copy of a file with a 7:18am timestamp on the DFS server in headquarters and an identical copy with an 8:18am timestamp on the remote DFS server. The file in question has a December datestamp.

This phenomenon is not present for files with DST-range datestamps, but is for all others.

Because of the way DFS works, I can't simply delete the remote files.

I'd like to use ViceVersa to overwrite files on the remote server that have a newer timestamp. It doesn't seem this is possible.

The folder hierarchy is pretty elaborate separated by subject/year/month for the last 10 years. Manually going thru each folder will be tedious. I was hoping ViceVersa could be used to just look at the root folder and all subs and overwrite just the files with newer timestamps.

Possible?

Yes, you can overwrite files with newer timestamps in target.
Maybe the best way is to do it manually.
Compare source and target then show only pairs with newer files in target.
Select source files and copy them to target.
