OK, let me show you a moment from the future.

Someday your OLTP server will die and be down for hours to days.

At that moment you will go flip a switch and put an exact twin to this
machine in operation and it will have an up to the minute copy of your
database.  As the twin machine will share zero hardware with your
production server it will not be down at the same time.

Your total unexpected downtime will be 5 to 10 minutes, depending on human
factors.

What will that twin machine have been doing all this time?  Running your
reports and extracting data for other users.

How will it be kept up to date on your live database?  Replication.

What do you need to do now?  Practice the speach to your boss.

"Boss, we have partners and customers who depend on our systems being
available all the time.  All it will take is one hour of downtime during
the middle of the day and we'll fold..."
