Unfortunatly the $500 solution will not work. Using this just creates a simple backup of the e-mail system. This gives a one time snapshot of the system when the backup is run and is normally overwritten when the backup is run again or as changes are made. What this requires is the saving a permanent archiving of all e-mail sent to or from the county entity. This requires working from the mail server at the county. This system would need to never lose data never delete e-mail or files, never alow the removal of files or data, allow the searching and retrieval of files and be off site (not in Walton County). This would be a private sector solution one that would have to be bought and paid for by County Funds meaning tax dollars. The $500 external hard drive will not do this. More than likely for simple backups the county already has servers assigned for performing this task on a daily basis.
