You know it's something I've never even considered, and it's probably something people may consider a stretch, but when you look at the benefits, it actually is.  Look at the facts:  according to the 2007 report by HP and SCORE developed a paper, Natural & Man-Made Disasters, they found that "70% of small firms that experience a major data loss go out of business within a year," which is pretty horrific.  Whether it's from a computer crash, a natural disaster, electricial fire, or a disgruntled employee.  Yes it happened to a student, who had noticed that there were numerous amounts of data missing after she took over a family-owned business and they let go the accounting contractors.

What does this have to do with being more green?  If someone doesn't have their data backed up, imagine how many countless hours an owner and their staff will be using to recreate customer lists, financial records, inventory lists, etc.  This translates not only into huge amounts of payroll expenses for your recreation time, but think about the countless hours of electricity use, travel to/from your business at all hours of the day, including weekends that normally you and your staff wouldn't be there, as well as additional office supplies that you didn't expect to use so you check and recheck the information is correct.

There are too many options out there for you to consider not pursuing this.  Two of the largest companies are Mozy and Carbonite.  Prices usually run in the range of $5 per month for the most basic service and a free 2-week trial, which you'll have to sacrifice a cheap drive-thru lunch or a caffe latte once a month.  If you're seeking the support from a small business such as yourself, where personal attention is important to you, Pack Rat offers 5 GB for $9.95 per month, with up to 3 months free if you sign up for a 1-year plan.  Above all else, is a back-up copy of your business information a better investment than a burger and frieds with that drink?
