using shadow copies with DFSR

I currently am running a new Server 2008 domain. We are using DFSR for our file server and I would like to use the Shadow Copies feature.

How does this work with DFSR? Primarily on the backup DFSR server? Does it have to enabled on both servers?

Anyone that has a similar setup and performed this please give me some insight. Do not want to mess anything up by enabling this the wrong way.

Thank you

There is only one way to enable it and that is by enabling it.  DFSR stores the shadow copy data (by default) in the system volume information folder of the drive it's protecting.  You CAN specify another drive provided you do so before you take your first copy.  Otherwise, you'd have to turn off Shadow Copies to move them.

As far as DFSR goes, there's no issue I've ever seen nor would expect.  I have this at a client where you use DFSR to replicate their two major company shares between two sites.

You should also understand that Shadow Copy does not make full "backups" of files - it only does things at the block level so it doesn't need to create a full 2 GB backup of a 2 GB file if ONLY 1 MB of that 2 GB file changed.

So since I have two servers in the DFSR do i have to enable Shadow Copy on, lets say for example, the D drive of both servers? Or by enabling shadow copy on the one server it will automatically allow it on the second one?

Shadowcopy is not a component of DFS.  Enabling it on one does not enable it on another.  Shadowcopy watches changes to the disk and on a schedule creates "backups" of it.  DFSR watches for changes on the disk and copies them over the network by default instantaneously. They work independently of each other.

Yes I understand that.

I am just asking if I enable Shadow copy on Server1 should I enable it on Server2. Will that cause any conflicts if I do or dont?

What is good practice if I have both DFSR and Shadow Copy running?
