It was in TR3466 which inferred it was supported (quote below from the TR)
"The NDMP listening port (default of 10000) can be modified during the install or using svconfigurator as well. This information is vital if using an NDMP management tool such as DataFabric Manager. By default the port is 10000. If you have another backup application (e.g., VERITAS NetBackup) installed on this system, you may need to use another port (e.g., 11000)."
However, I downloaded the lastest version of TR3466 and it is no longer listed in there. Does OSSV set an archive bit? I am not sure if it crawls based on last update date or by setting the archive bit.. Can anyone confirm support for both an NBU 6.5 agent and OSSV on the same host? It was mentioned in the prior version of the TR and no mention in the release notes or user guide if there is contention.
