I have a system where some of my projects are copied to backup servers. Tags exist on the primary and backup servers for redundancy.

We only have one database, and I don’t want the backup servers to write historical values for the tags, however I would like to have the history active so the trends can be populated with data when the main server is available. Is there a way to do this?

Thanks!
