Bernie1969 0 Posted January 29, 2016 I have a generic h.264 system with a 500 gb hard drive and Linux OS. It records for 30 days and then overwrites. I have a 3 tb external hard drive and I would like to backup the system just before overwrite begins each time. Is this possible, and if so, how do I get it to happen?
