Is Linux rsync Supported in Production Systems for Middle Tier Disaster Recovery Synchronizations?

I am following this guide to setup the DR site:

In section 4.5.6 Using Peer-To-Peer File Copy for Testing, there is a note that states rsync is not supported in production systems.

Note: the client's environment has all product binaries and managed server domain files on local files systems, where rsync as mentioned in the DR guide seems to be preferred method to do these file copies.

The client does run NETAPP's NFS 4.1 servers so for the shared files systems, the client is considering using NETAPP's capability to copy the shared PROD data to the DR.

Is this true?

If true, what utility is supported to do PROD to DR data synchronizations?

Here is the note in section 4.5.6 that mentions rsync is not supported in production environments:

Note the following important differences between using storage replication technologies and using the rsync utility to replicate middle tier file systems:

• When you use storage replication, you can roll changes back to the point in time when any previous snapshot was taken at the production site.
  When you use the rsync utility, replicated production site data overwrites the standby site data, and you cannot roll back a replication.

• When you use storage replication, the volume that you set up for each host cluster in the shared storage systems ensures data consistency for that host cluster
  across the production site's shared storage system and the standby site's shared storage system. When you use the rsync utility, data consistency is not guaranteed.

Because of these differences, the rsync utility is not supported in production environments but in test environments only.
