There are times when you need to perform simple maintenance on your files.
I’m talking about backing up your stuff.
You can back it up to the cloud so you can access your stuff anywhere, you can download copies to an external hard drive (these are pretty cheap nowadays), you can leave them on your work machine… However, I don’t suggest the latter. This is life, and things happen.
Back up your stuff. Once a week, once a month, once every couple of months. Just do it. It’s simple, and it will eventually save you a lot of heartache.
