Even if you take good care of it, you should never keep anything important saved in one place. All it takes is one thing to go wrong.
This is why I keep my character art saved in like three places now. I ended up losing one somehow, which was a little weird because I'd remembered using it not too long before that to make an icon. I couldn't find it anywhere, and I know I didn't delete it or anything, but luckily someone else also had it saved, so I got another copy and immediately made sure I had it in more than one place, just in case something odd happened again.
Whether you take good care of your things or not is irrelevant. If it's important, keep a backup.
