2. Start creating nightly data backups
This measure goes with the first point. Without backups, you are completely lost. So making regular, reliable backups is the single most important thing you can do to prepare for a disaster. What's more, you need more than just a backup to an external drive. You must also have an offsite backup. As long as you have data, recovery is always a possibility. Make sure backups are nightly and successful. Backups are not a matter of set it and forget it.
