The Problem
I've been busy composing a new PC for myself.
The problem I always encounter is storage. One always needs more! I remember how happy I was with my 286 with 20MB of storage! How incredibly spacey the ensuing 486SX was with a whopping 250MB harddisk! And now? I've got 160GB crammed with stuff, a box full of DVD's containing all kinds of things and the end is not even near. So I was thinking to myself and I think I'll spend my hard-earned cash on something else.
Local versus Online
Storing anything locally is actually a bad idea because of the major issues with continuity and especially reliability.
A virus breaks out, wiping half of your harddisk: data gone.
Your hard disk crashes: data gone.
CD's en DVD's rot: data gone.
Filesystem breaks down: data gone.
The local computer"expert" decides your PC needs a thorough makeover and doesn't back up your only partition: data gone (and the stupid look on the guys face when he says:"o, I didn't it had to be saved").
And don't think it won't happen to your stuff, everybody is at huge risk. With all the recent developments in the hard disk and optical storage worlds it is increasingly difficult to tell how stable a storage device is over the course of a couple of years. Remember one the principal selling arguments for the CD was that it had no wear and tear. By now we know so much better.
In short: Everything that's stored locally is under a constant threat of being lost. And so I'm a so-called Service-Oriented Architecture evangelist. Store as much as possible to trusted third parties. Consider how much you could permanently save already by moving it to someplace on the internet?
Remains only the larger stored stuff, like photographs, movies, music, projects and the like, and other miscellaneous stuff that can't be stored online like chatlogs.
Although there are a multitude of solutions for photographs to be stored online I consider none of these a serious option because they always carry too low a limit and/or compression factor, inexcusably downsampling the image. Aside from that a number of things can have continuity- and trust-issues.
So, to get around these things the only way at this point is to store locally anyway.
However, I think it's safe to conclude that we have to do that redundant and fail-safe, because the aforementioned scenarios are nightmares you wish upon nobody and which have happened all TOO often in my experience.
Birth of an Idea
One evening a couple of friends and I were joking about how relaxxed it would be to store your entire digital life on a single system. When fire breaks out you'd only have to get one single box and carry it out to save EVERYTHING you hold valuable from certain fiery doom.
Although the idea made for a couple of good jokes and caused quite some hilarity, it's actually quite serious. Whenever you need to evacuate your house for whatever reason within 5 minutes just about anything you hold dear remains behind. Especially photo-albums and other personal collections are always tragic losses, both in terms of personal attachment as, more pragmatically, invested time. Projects and hobby's which currently are spread out across your computer system(s) are also lost beyond rescue.
All things considered I think you owe it to yourself to take care of this data, and apparently a single hard disk won't do for that.
