With the Oscars just 3 days away, movies have been on our mind lately here at CDC's Office of Public Health Preparedness and Response.  Especially disaster movies.  They come in all kinds of flavors: deadly viruses, tornadoes, earthquakes, and, yes, even snakes on a plane.   Their special effects can be realistic enough to make us feel like we are right there in the heart of the storm.  But frequently, the heroes and heroines of these movies respond to disasters in ways that bear no resemblance to what people in the real world should do.  We can nevertheless use disaster films to consider how the characters could have been more prepared or how they should have reacted if the situation they faced was real.  Check out some of our favorite disaster movies and the lessons we can learn from them.

If you pay for web hosting in order to run any kind of web-based application-from your WordPress blog to a nameplate site to a file-sharing service to a social media data archive-you need to back up your web server's data the same way you back up your computer's data. On database-driven web sites, there are two kinds of data you want to preserve and restore in case of disaster: the files that make up your site (the PHP/Perl/Python, JavaScript, CSS files, etc), and the contents of your database. Further, any good backup system should make both a local copy and a remote copy of the backed-up data.
