If you're like most people, you are steadily building up a stockpile of digital memories and media that, it would be assumed, you hope you will be able to appreciate for years to come. But that's the tricky part, isn't it? Most of the time there is no physical copy of digital pictures, nothing you have printed up, and there are right on no negatives you can lock up somewhere to retain into the future.
Digital pictures (and music) are very brittle in the sense that they are nothing else but lost, field to the reliability of electronic devices.

The thing I find intelligent about this qoute - about the fickleness of storing your personal and sometimes very foremost digital facts - is that it is getting cheaper and cheaper to store large quantities of data, the price of hard drives has fallen greatly in relationship to how many gigabytes of capacity they have. And that's great, except for one thing: the more you can store on your hard drive, the more you pile on, the more you are going to lose when that drive fails.
And make no bones about it, every hard drive will - eventually - fail. In other words, replacing hard drives and protecting your memories is a constant game of cat and mouse, is a constant game of trying to stay one step ahead of degradation and mechanical failure...it just never stops.
But the way I see it, there are two ways - and I use them both - to eliminate some of stress associated to losing valuable digital data: burn your own Cds or Dvds (often) and put them away somewhere, and use an Online Backup Service.
