I work a lot with security DVRs, and one question I get asked a lot is how to quickly and reliably replicate the video data in real-time to a second server on the same network.
Most of these systems create individual data files for each recording event, so the issue of copying an open file is not a problem. The amount of data is typically small, as only the incremental changes need to be copied.
These boxes are generally Windows XP OS, but I’m experimenting with Linux security DVRs at the moment as well.
I have not used NAS devices very much, and if they have this capability built-in, then I’m all ears.
I know I could create a VB script or scheduled batch file to just copy the data, use Windows backup function to copy the data over, but I assume there are better options.
It would be nice if it had some logging or alerts to show if the process is working or has stopped.
So the question is what is your favorite data duplication/syncronization application?
