running a production string into the wellbore, the production string comprising production tubing and completion components including a first packer with a first control line and a backup packer with a second control line;
setting the first packer in the wellbore in response to a signal on the first control line;
producing hydrocarbons from the wellbore with the first packer set and the backup packer unset; and
setting the backup packer in the wellbore in response to a signal on the second control line, wherein the signal on the second control line to set the backup packer is sent in response to a pressure applied to the backup packer.
