There’re only so many times I can say it.
If you do work on your computer that you can’t afford to lose – whether you’re a writer, artist, designer, whatever – you need to sign up for and install dropbox. Not tomorrow, not in ten minutes. Now.
Dropbox is a free backup service. Once installed, it creates a Dropbox folder somewhere on your compie. Anything you drop inside that folder will be mirrored to the Dropbox servers, where it’ll stay encrypted and safe. When (not if, WHEN) your hard-drive implodes, all your Dropboxed files will be safe and up-to-date, because every time you modify and save a file in your Dropbox folder, it updates the remote copy automatically.
Just to clarify, though – Dropbox isn’t an infinite file-dumping area. It’s a mirroring service. That means, everything in your Dropbox folder will be copied exactly into the remote Dropbox server. Add a file in one, it’ll appear in the other. But if you delete a file in your home Dropbox directory, it’ll vanish from your online backup as well.
On the other hand, this means you can install Dropbox on multiple computers – home PC, laptop, mobile phone – and every time you boot up any of those computers, all the files in the Dropbox folder will be updated to the latest revisions. Automatic synchronisation of your most important documents across Windows, OSX and Linux. Awesome.
So, in summary:
1) Download and install Dropbox.
2) Put everything important (up to 2GB) into the relevant folder
3) Keep it there, even as you work.
Seriously, this is 2011 and we’re all tech-savvy folk. There’s no excuse for losing data to HDD corruption, and no matter how immune you think you are… all hard drives fail.
