So I've just upgraded from Maverick to el Capitan via the "Upgrade" button in the AppStore. I like to have a USB bootable backup but cannot find the "Install OS X el Capitan.app anywhere in the /Applications folder. Anyone got any ideas ?
To the best of my knowledge, the OS automatically deletes it after the install. What I do, is to copy it after it downloads from the app store, but before I run the installer. You can re-download it in the purchases section of appstore.

The installer for OS X self destructs (deletes itself) once the installation is complete.
If you wanted to make a USB installer, you should have done that before performing the upgrade.
