To create a recovery disk, you need a USB flash drive or an external hard drive that has at least 1GB free space.
The simplest solution is to put an external USB drive or SD card into service using the OS X Recovery Disk Assistant. However, if your Mac is not online, or if you’ve upgraded an older Mac to Yosemite, that method won’t work. This recovery system is stored on a hidden partition on your Mac’s hard drive - but what if something happens to your hard drive? Well, if your Mac can’t find the recovery partition but it’s connected to the Internet via either Wi-Fi or a network cable, it’ll start the OS X Internet Recovery Feature. Start your Mac and hold Command + R to go into recovery mode, from which you can start Disk Utilities, restore from a Time Machine backup, or perform a clean install. OS X 10.7 Lion did away with recovery disks, and these days, Apple provides a built-in recovery system within Yosemite.
