|We've all wanted to go Office Space on our computers at some point.|
Computers crash. Electricity goes out. Windows likes to apply updates (every freaking day). Random virus seep their way in. To put it gently, stuff happens. When it comes to your documents, it's better to be safe than sorry.
Autorecover and Autosave
Easiest thing you can do. You click a box, select how frequently you'd like Word to autosave. Check here for instructions.
But what if your computer is as reliable as the car I had in high school (read unreliable)? Simply saving to your hard drive might not be enough for you to sleep soundly. No problem--there's plenty of other options!
A (free!) online service that stores your documents somewhere else (that illusive netherworld again). Create an account and upload your files. You can even sort them into folders for organizational purposes.
Invest in a super cheap thumb drive or splurge for the more expensive yet more roomy (geez, sounds like I'm selling cars) external hard drive.
Good 'Ol Fashion Email
Have an email account? After every session you can send an email to yourself with the document as an attachment. Create a specific folder in your email to send all the attachments to and now you have a time-dated record of drafts in case you want to revert to an earlier version.
It's a few extra minutes and can seem overly cautious, but well worth it!
