  • External Backup of Data files - It's important!

    In addition to doing the regular backup that is built in to the CORE program it is important to conduct a weekly or monthly external backup of the CORE data to prevent loss of critical data in the case of;

    • -Computer Crashes
    • -Hard drive failure
    • -Virus Infection
    • -Physical Computer damage
    • -Theft

    Be sure to store your external data backup in an offsite location from where the CORE program is housed. Do not keep your external drives plugged in to the computer. If a virus hits your computer and the external drive is plugged in it can corrupt the backup.

  • External Data Backup Instructions:

    You will need to have a file storage device such as an external hard drive or a USB/Flash storage device.

    Go to the Configuration Tab in CORE it will show you the current drive and directory that your COREDATA files are located on. If it says the C:\COREBILL\COREDATA, then you are set to proceed with the direction listed below. However, if it has any other location you will need to find the correct drive that is listed on your table directory screen then proceed with the directions below.

    • 1. Go to My Computer
    • 2. Double Click on the C Drive
    • 3. Double Click on the COREBILL folder
    • Copy the COREDATA folder and paste it onto your storage device

    Once the file is on your external storage device, re-name the file to add the current date at the end of the file name. Example: COREDATA12-16-16. This will help keep track of when the backup was done.
