Did you answer NO to any of the questions ?  If you did then Software Support Pty Ltd has all the solutions for your backup procedures, from a couple of megabyte to hundreds of gigabytes

Why protect your data? 

Human error. It's easy to overwrite a file by mistake. Type "Y" when you mean "N". Or even delete it from your hard disk by accident. Most data loss is caused by human error

Hard disk failure. Like most motorised equipment, hard drives eventually fail from old age. They can also be damaged in moving and shipping. Neither is predictable. And either way you'll lose all or part of your data.

Fire and theft. With a single copy of your important data saved on a single hard disk, you're extremely vulnerable. You could save your data, and possibly your business, with a backup copy stored off-site.

Power spikes. Sudden power losses or spikes on a system with out a good UPS can cause unrepairable damage to computer hardware and corrupt data, both of which result in unrecoverable losses. 

And lets not forget viruses

Would you lose any important information if your hard drive crashed today?
