Before copying anything, we need to determine what to copy. In some instances, it might be necessary to copy the entire database for disaster-recovery purposes. At other times, such copying would waste resources. We need to differentiate between these two scenarios.
Once we've done this, we should decide what to do when we don't want to copy the whole database. We need to know which tables to copy and where to send them. To accomplish this, we will build a very small spreadsheet in this section to keep track of the resources we will need for all of our table and database replicas.
