I'm a big fan of making backups of important files by e-mailing them to yourself. For example, suppose you just finished a lengthy school paper or business presentation. By e-mailing a copy to a Web-based e-mail account, you immediately have a backup that lives "in the cloud."
Presto! The program instantly sends your file(s) to your Webmail account. Obviously you can do likewise with your everyday e-mail client, but that requires considerably more clicking. This is a two-click timesaver, one that I hope will encourage you to make on-the-fly backups of critical files.
After all, you never know when disaster may strike your PC. (I know, ominous, right?)
