So, restoring the config database is not recommended, but what happens if you do it anyway? In theory, things could be out of sync, but in actuality, what exactly could get out of sync?
So, for example, at 10:00 pm, backup all SharePoint databases. 10 hours later, restore just the config database. In those 10 hours, no sites, web apps, or anything else were added/removed.
So now what happens?
Does the farm function normally?
Is there any way to use SharePoint tools to know that the config database has been restored?
