Today my old faithful laptop that I worked on daily for the past 6+ years crashed. I tried to recover it, to no avail. I tried the disk that puts it back to factory setting, that didn't work either.
I do most of my work on the web, so am able to reach many of my income sources, but hundreds of files are now gone...picture files, my important bookmarks to web pages, documents from some family matters I kept track of, and so much more. I think I can live without these things in some ways, but won't really know until I go to look for something and it's not there.
So now I do wish I'd backed up my files. It's going to be interesting to see what the coming days and weeks bring. I will occasionally be able to work on my husbands desktop computer...when he doesn't need it...like right now.
DO back up your files, especially if you are using your computer for your home business, or have important documents stored on it.
