It is crucial to have your QuickBooks file accurately backed up. Good backup meaning that your data file does not have error on it and if you ever loose your power connection, you can quickly reconnect and your data is not lost. Yesterday William (Will) drove to Laguna Beach, CA to assist one of our clients. He reconnected their QB Point of Sale (POS) with their server because they lost the connection. It is so important to have a system with a redundant hard drive and current backups.
