Backing up your business data is a great idea as you never know what may go wrong with your computer or office space. A separately stored hard drive, USB or disc is one way to keep your records in duplicate just in case. Protect them and everything else you keep online with a password so that you are at less risk should the information get into the wrong hands. Alternatively, if you store everything on your computer you can consider storing it in the cloud so that it can be accessed from any web browser.
