I 've been using computers for 20 years and I have gone through several styles of backing up my files. In the past I used to burn files on CDs and DVDs, which soon turned into a huge mass. I couldn't archive them and usually when I needed a file I should search through hundreds of them.
Then HDDs got cheaper and I bought some 500Gbytes devices. I backed up my files on two hard disks at the same time in case something fails and this was a more professional procedure to follow. Unfortunately, last year I was a victim of home burglary which was a big disappointment for me but fortunately they didn't took away my hard disks.
I realised that they could steal my hard disks or/and DVDs and then years of work and memories (photos, videos) could fall on criminal hands, exposing my personal life to everyone and erasing my memories and my work. So I had to find something more secure, efficient and affordable. And I found crashplan which backed up my files encrypted in some place secure and kept intact from burglar attacks, fire, destruction or whatever.
I want to secure my files insanely, especially my childhood memories and work. I am looking into insane but serious ideas to do so. I am also being sceptical about companies that shut down one after the other (like springpad for example) so I don't want to rely on the cloud only. I am also looking for cheap solutions, meaning that I do not have the capital to maintain three RAID servers around the world and one in my home.
