Migrate redirected folders to Distributed file system

I have a windows 2012 R2 virtual machine as a Domain controller.
On this DC I have installed windows server essential https://technet.microsoft.com/en-in/library/dn280940.aspx 
Have redirected users's desktop & mydocuments (folder redirection) to shared folders on this DC only.
Have others shared folders too with different security permissions on the same DC.

Now I have setup an additional domain  controller for fault tolerance/ replication.
How to replicate these redirected & shared folders to additional DC? I have a NAS too, may use that too if you suggest. (http://www.downloads.netgear.com/files/GDC/datasheet/en/RN100.pdf)
I guess, I should setup Distributed File System (DFS) Replication.
But how to migrate all these redirected folders without disturbing users to DFS?

I suggest that you first define your requirements.  What problem or scenario are you trying to solve?

How much data are we talking about?  What is your current backup/recovery plan?

The two things you really need to determine are your recovery time objective (RTO) and your recovery point objective (RPO).

Recovery time is, "how long can you take to get your data available to your users?"  15 minutes?  4 hours?  1 day?

Recovery point is "how much data are you willing to lose?"  Do you need to restore to a point 15 minutes ago?  4 hours ago?  Last night?

Once you've decided on these figures, you can start finding options that meet your needs.

Data is about 200GB that can go at the most to 500GB.
I am ok with last night data restore.
Ok with 3-4 hours downtime but trying to minimise the downtime.
I am doing daily backup at night using windows backup software. Backing up bare metal backup of all the VMs. But sometime these backups fails & I am not trusting the backups.
Don't have budget for symantec or common vault backup solutions.

I have spare previous server machines. So has set up that machine as additional domain controller & hot standby DHCP. As the data is on primary DC; I want to replicate the data on ADC. In case main DC machine hardware fails, I could use ADC with shared folders & redirected folders.
In that case, DFS replication is probably your best bet.  I don't really see the need for migrating everyone to the DFS namespace, though.  All you'd need to do if the primary site goes down is to pop in a CNAME record that points to the second server.

The query is still the same; how to move redirected folders to DFS.

I quit the idea of replicating through DFS feature.
If I would use DFS, I can't take backup from the host machine of the VMs; restoration would break DFS replication.
