Risk Management Questions
Q1. Why do I need an Uninterruptable Power Supply?
A1. You need a UPS to improve the delivery of the mains power to your POS System and you should also use a Power Filter to improve the quality of the mains power. The Australian Power system is designed to power electric motors not computers. A laptop computer and some POS terminals have an internal battery so a UPS is not a requirement in these cases. Not all UPS devices are equal. Specify a Line Interactive Type and do not select anything under 500VA.
Q2. Which POS Terminals and POS Computers should I fit a UPS and Filter to?
A2. Ideally all of them and all communication gadgets such as the network switches, EFT POS equipment and modems used for data transfer. Do not plug heating devices into UPS Power Supplies. Eg Laser Printers and Vacuum cleaners or Hot water jug as examples. Thermal Docket printers are OK
Q3. What is the minimum number of UPS and Filter I could use?
A3. One on the computer that houses your Stock, Customers and Suppliers. This could be a File Server or a Back Office computer.
Q4. How should I do my data backups?
A4. There are many methods to suit many businesses. The Main Criteria is to do data backup daily, also backup to another computer and also to take the data off the premises daily. The backup should be restored to a different computer so you know the system is functional.
Q5. What is the best method of backing up data?
A5. The best method is the one that allows you to restore your services in the minimum amount of time. Ask your IT support people how long would it take to restore your service using the backup method they recommend.
Q6. Do I need Virus Checking Software?
A6. Every computer in business is at risk of a virus attack. Keep away from the Free version of anti virus software as the software is not updated as quickly as the licenced version. It can be up to 48hrs behind.
