This is why TimeMachine quite frankly in my opinion sucks.
Want the best method? Clone your boot drive, the whole frigging thing whenever you have a sound and and stable configuration. Carbon Copy Cloner is donationware and reliable.
Hard drives are cheap, so have two clones, one set back a month or the last OS update and one done every week or every two weeks.
Clones are "hold option" bootable, which makes it real easy to boot from and recover, repair and/or simply reverse clone.
Hard drive crashes one morning? Just boot from the clone and you can get online in the time it takes to boot. Can't do that with Time Machine and a OS X install disk alone.
Naturally clone your present configuration before a OS update and this mess would have been avoided, you control when to clone, thus you know when and what clone to use.
Backup your files to a USB drive or two daily and then your set.
Look in the Genius help section of AppleInsider for my cloning method.http://forums.appleinsider.com/showthread.php?t=32364
Keep a very detailed and updated copy of all your product codes, related information and disks/websites and passwords in a safe and secure place to facilitate the speedy recovery in case you need to do a complete reinstall of OS X and apps from original sources (more secure).
You should do this regardless once a year just to clean out anything or something that may have invaded your system before a patch was issued via applicaitons (most likely method)
Use ClamXav, it does catch a rare thing once in a while.
Keep your hard drive less than 50% filled for best performance, it starts to degrade more than 50%.
Whenever you start using a brand new drive, always, always DiskUtility>Erase with Zero option a brand new drive. It maps off any bad sectors and improves reliability of data and OS.
