Practice your disaster recovery plans so you'll feel comfortable when you have to put them to use. If you don't practice them, two things happen. First, you won't be confident that they'll work and, second, you might feel unsure of the steps you need to take. Say, for example, you have to migrate a database to a server at a remote site. Do you know the commands to run? Is the database dump ready now or do you have to create it? Do you have any idea how long it will take to move the file? Will you be ready to bring up the database on the remote site? Do you have a set of tests to verify that it's running properly?
