Using Cloning as a Backup Strategy
http://macperformanceguide.com/Mac-HowToClone-backup.html
Trying to find the pea under the mattress or the needle in the haystack is what is hard, time consuming, fruitless, etc. I know people want quick fixes and wave wand or incense or magic.
Magic is having a bootable backup clone; Disk Warrior; and an alternate up to date drive you can boot from and use.
And it is easy. Of course doing it once - the fruit is in the tasting and then you have the experience of the pie, and the confidence of how to.
Hand holding or using a cane can make one more dependent on the cane (I know that lesson) and relying on training wheels.
Multiple backups, a recovery plan that has been tested at least once.
SuperDuper or Carbon Copy Cloner and they already HAVE tutorials and guides, someone wrote their pdf manuals. There are Help in the HELP menu though no one looks anymore and wants what? spoon-fed? Disk utility Help tells how to "clone" (they call it restore) a disk partition and how to erase.
And in earlier reply, How to Clone: did you notice? it has screen shot images of what to expect!
