If you don’t backup your data onto diskettes or tapes you could lose all of your information should your computer malfunction. It is essential to backup every day, using a different backup set for each day of the week. Also, unless your store’s electrical power supply is perfect, you should get a UPS (uninterruptible power supply) for your computer to prevent power fluctuations and outages from damaging your data. A UPS is a battery for your computer which keeps it going even if the power cuts out. It also provides the correct power to your computer if the electricity level is temporarily too high or low.
