comment Is DFSR designed for use for Disaster Recovery?
How does storage replication or SAN replication solve the problems that you just identified with DFS-R? They are all vulnerable in the same way.

Any good DR plan has multiple layers to it. DFS-R can ensure that critical shares are available quickly while proper backups (and the ability/equipment to restore them at the DR site) can protect you from the scenario you've described.

Think about non-shared resources like home directories, read-only archives, etc. Those are all excellent candidates for both DFS-R and DFS-N. Additionally, you can use a namespace to direct all users at a single replica and then flip it to the other in the event of a failure. There's no mandate that the load be evenly distributed in a DFS-N scenario.

[...]conflicts especially if both servers are being used like a proper failover (so users are hitting both servers at once). - The DFS-R documentation is very clear that it is not a good solution in scenarios where the same file is accessed on multiple replicas by different users. In that case, a proper collaboration solutions (like a SharePoint document library) is appropriate.

What are you looking to protect with DFS-R? Just file shares?

Please re-read my comment. The OP asks if DFS-R is an appropriate technology to protect a file server in a DR scenario. You say "no." In fact, it's the first word in your answer. I'm asking you to explain why you don't think that it is an appropriate technology. I understand the value in SR, but I don't understand why you don't think DFS-R is appropriate.

Backup isn't always synonymous with DR. Can you explain why a DFSR Replica isn't appropriate for a file server DR scenario?

comment How to check if any malevolent scripts are running on the server?
No. I'm not kicking you. Centos 6 is an Operating System. Ubuntu 14.10 is an Operating System. Both have a Linux kernel and both behave rather differently in many cases because of the vastly different userland
