We're implementing a DR solution consisting of HA MySQL servers using always on availability groups along with an NFS file share to host our data folders. Our DR sql server currently is configured to asynchronous commit mode so there's always a chance for lag. The NFS file share is not realtime which is an issue we're addressing so its possible we could lag an hour between whats on the primary share vs secondary. My question is, whats the fault tolerance between the database and fileshare? Would teamcity experience catastrophic failures if there's an hour difference between the database and share? I'm going under the assumption we'd see strange behavior but would like to know what the expectations are specifically between the database and data folder.
