If user does save previous version of file from VSS, the restored previous version gets replicated to DFSR partner

If VSS is enabled on both replicated partners, the last restored file will win and replicated to all partners

Note that since VSS copy is server specific it will not get replicated across DFSR partners
The VSS versions of same file on both servers can be different based on time difference of VSS snapshot is triggered
If VSS snapshot is triggered on all replicated members at same time, you would get previous version data similar on all members, note that this is workaround as VSS copy is separate for every member

I hope this is clear

In this article I will cover Microsoft DFSR major issues and their resolution. These issues can occur during initial deployment or post-deployment. The resolution for each problem is available on the internet generally in standalone posts. I have tried to present them here collectively and detailed.

Hi Mahesh

For issuing a new Sub CA certificate from an offline Root CA, do we need to renew and publish a new CRL from the root CA?

Thanks in advance.

NO

CRL need to be published in two cases
When your existing CRL validity is expired - You should have keep CRL validity period good enough for Offline Root CA, say, on e year
OR
if you have revoked any certificate

I would add that you REALLY SHOULD store snapshots on a separate volume. The reason is that Windows may DELETE your snapshots stored with the parent volume during high disk IO. Imagine you have a large restore to do on your file server, so you do a smaller test restore first. It works, but the act of restoring creates so much IO that the other snapshots get deleted...the same snapshots you were about to use to restore from. Ouch! I have heard about it happening. It's the first best practice Microsoft lists.

Actually, I do recommend this...
"BUT WAIT! Before enabling, if you want to place your copies on a different volume or better still different physical disk (recommended for heavily used file servers), you need to click on the settings button before any copies are created (enabling a volume will instantly create a copy)."

Good and useful article, but a warning to users who may read this: It is not recommended to just try and delete system files. Without going into a long explanation, if you use Lee's method above and find a lot of space being taken up by a specific directory, search on how to clean up that directory. Here is an example for one common place that files build up:

You might have come across a situation when you have Exchange 2013 server in two different sites (Production and DR). After adding the Database copy in ECP console it displays Database copy status unknown for the DR exchange server. Issue is strange though but both Exchange logs are replicated.
