My laptop is may main computer. My "backup" procedure consists of cloning the
C: drive using a freebie utility called "xxclone" (http://www.xxclone.com).
This one is one of the best cloning programs that I've tried and being free is
a double bonus.
The target drives are the same brand and size as what is installed in my
laptop. The bare target drive is connected via a USB-to-EDIE interface cable
that I picked up somewhere on the net for about $20. I use 3 drives in
rotation so that I have 3 generations of drive snapshots at any given time.
That has saved my cookies more than once when I realized after the last clone
that I'd deleted something vital. The three "backup" drives stay in my
fireproof safe inside zip-lock bags. The zip-lock bags are vital. I learned
the hard way during a house fire that even though the fireproof safe protects
the media from heat, it doesn't protect it from the acidic smoke and steam
that are drawn into the cool interior.
If the drive in my laptop fails, I don't have to do a restore. I simply get
the latest clone drive out of the safe and install it in my computer and I'm
instantly back up and running with the machine state being that of the last
I do a weekly clone and a daily differential backup to my linux file server
running SAMBA using another freebie utility called SyncBack. A flash drive is
another option for those non-networked computer users.

worth of changes easily fits on a 4 gig flash drive.
I still have the occasional nightmare when I think about tape backup. More
accurately, the time wasted verifying each tape and even then, having the tape
not read about half the time when it was needed. Never again!
