Time Machine is a good safety precaution to have in place in case you need to recover a file, or roll back your system after a bad update. But you should also make a complete backup of your Mac in a good state, and optionally update that backup on a schedule. Case in point: while writing this feature, Time Machine on our MacBook said it needed to start backups from scratch. Carbon Copy Cloner is a great app for doing this, and you can even start up your Mac from the backup it creates to avoid a lengthy downtime.
