Veeam agent CIP compliance

[Technomojo]

This may be answered elsewhere but I could not locate. I am also not sure I am asking this in the correct manner.
We have a NERC CIP controlled critical network that is essentially a dark site and has no internet connections and does not communicate with any outside network. There are a few sub domains in this network. The Veeam server / storage location will sit outside of this network.
We need to know if the Veeam agent can perform system backups that are client initiated and ONLY require network communication one-way from the client out to the backup server / storage location?
