rotor123 suggested an as close to perfect solution you can have for saving data at a consumer level.
I have a couple of WD 1TB Blacks and several docking stations that get most of the backup data. Real, real important stuff (stuff the wife deems important) gets put onto DVDs and Blu-rays as needed. The WD drives stay packed in their shipping containers in the original conductive wrap when not in their stations. I never have less than 2 independent copies of backup at any time, and including my optical media, 3 copies at all times, 4 copies if you include my USB drives in my safety deposit box.
Good FUJI and Verbatim DVDs have been solid for over 10 years, and I check them. I keep an old BenQ DVD drive around and when I feel like it, I can do quality scans to record the PI/PIE/PIF/P0 numbers. High error readings are a precursor to data loss. I have burned several Blu-ray disks, but haven't gotten around to do quality scans yet.
How you store data is darned near as important as what you store it on. Learn about PAR files (QuickPar is my favorite). Break your files up with something like 7zip, compress them, run Quick par to generate your PAR files and your data can survive anything but essentially a catastrophic disk failure.
I see it so often in my work. Dead hard drive and some parent with 5 years of kids pics and videos that may be gone for good....and no backup.
