Right now. Before you do anything else. After all, you’re a DBA and backups should be in your DNA. You should have taken one prior to the start of any upgrade or migration, and you had better take one right now, and again before you turn the database over to end-users. Also, you should save any output from the items listed here, as doing so could prove helpful should something go awry later. And don’t forget to make sure your backups are good! […]

I’m guessing it is involved in getting the magic 1.96 number, but unless we know how, there is no way the reader can use this method to determine how many backups they need to test in their environment. (Unless they also happen to be responsible for 3000 databases as well.)
