We run Zoho Analytics On-Premise, with a license for two servers, one each in two different physical locations. We run one location "primary", with the other site serving as a "hot backup" that can be switched to if something happens to the primary site. While some services need up-to-the-second syncing, for Zoho Analytics it's OK if the data on the backup is slightly stale (say, a day old).

I'm trying to figure out the best way to setup a "hot backup" of Zoho Analytics. Naively, seems like something like this would be the way to go:

This won't work completely, though. For one thing, both servers need their own license, and presumably I need to do something to prevent the rsync from overwriting the backup's license. Would excluding the 'conf' directory from the rsync be sufficient for this?

Maybe syncing just a subset of the Zoho Analytics directory (e.g. just the database) would be better?

Maybe there is some better way to do this?

Maybe there is a document that explains this that I cannot find?
