I'm a proponent of backing up data. This usually means your computer's hard drive but this also applies to many different places. A couple of weeks ago, I was tinkering around with my website and I tried to change something that I wasn't supposed to be changing. Next think you know, I refresh my site only to find an empty page. I'm no PHP wizard so I'm not exactly sure how I messed things up. I also wasn't sure how to fix it either. Luckily everything you see here is backed up somewhere else. In fact, I even have the original incarnation of my site, which I hosted on Blogger up until this year, backed up on my computer. It wasn't exactly an easy task to bring everything back but the most important parts, the images, layout and posts, were archived so I didn't lose any data. Another disaster easily avoided by simply backing up data.
