While we all know how important it is to save our work and make back-ups of those important files, just in case...it is often in retrospect that we "wish" we had done things differently. Well, at least in Microsoft Word, you can create an automatic back-up of your files. These can get annoying, so you might want to turn them on and off if you use Word a lot. However, use it if it's something that makes sense for you. The backup file will have the .bak extension. Excel has something similar, but it's more of an autosave than a back-up file.
Here's how you turn this feature on in Word.
Go to the Tool menu bar and select "Options". Click on the "Save" tab. The first item should say, "Always create back-up copy". Check that, click OK and then you are set.
Don't forget to save your work on your H drive or the server as well so that in case of a hard drive failure you will have another copy!
P.S. There is a third-party solution available for PowerPoint that I found from a Microsoft poster on their site. I can't vouch for it but it might be something worthwhile for our IT group to look into.
