Save yourself and your employees headaches: Install a reliable software program that backs up your daily computer files. A cost-effective option is Atrieva (www.atrieva.com), which provides automatic file backup over the Internet. After you download the software, it will scan files created or modified every day for viruses. Plus, it will squeeze your files onto less space, encrypt them for security and transfer them through cyberspace into its own private storage facility. Cost: Backing up 100MB of text is about $10 a month.
