The only way you get reliability is with redundancy. Don't just back up to one place, back up to several different drives.
I used to do full compressed backups, but these days I can't be bothered. I back up my personal data, and that's about it. And I don't compress it. The last thing you need when trying to recover data is compression problems. I back up to four different places -- two hard drives inside my PC, a portable 2.5 inch external drive, and a thumb drive. I rotate the backups, which I do manually. It's a chore, but if my primary boot drive crashes, it won't be a tragedy.
This guy gets it. Reliability comes not from 100% reliable hardware, but a strategy that doesn't rely on any one (or more) drives not failing at the wrong time. Anyone who has critical data on just one drive is counting the days until they lose it all and being faced with the choice between giving up or spending hundreds or more on data recovery.
