But it would have me double my backup system. That is, my system is a layered approach with a full image to some external drive using CLONEZILLA. This takes overnight but the reason I let it do it overnight is it's over an hour so I give it the night to do its thing.

Next I have my files. I use GOODSYNC, SYNCBACK and DROPBOX and this gives me another way to reclaim my files.

Finally I have my high value files on a few memory sticks.

I used to use DVD media but that's slow compared to today's systems yet my "what I never want to lose" is on a few DVDs.

Hard drives can make noises but that's not a sign it's gone unless it's THAT SOUND OF MARBLES AND WORSE. I'll defer to the hard drive maker's test program AFTER I BACKUP.
