tomo_76 0 Posted November 2, 2016 Hello All, I am having problems backing up a few hours of video to a USB drive. My NVR is Samsung SRN-472S I have included a picture of the options I get when I choose backup in the options. The external USB flash drive is instantly recognised. After I choose the date, time and cam one the OK button at the bottom is still greyed out. I noticed near the bottom it says PATH and these numbers change to match the starting point to back up but when I enter the END info at the top these do not show up in the path at the bottom. I don’t really understand what PATH is for. There is also a drop down menu next to TYPE giving me the option of NVR or SEC I’ve tried both and still the ok button is greyed out. I have also tried using another USB flash. Thanks Scott Share this post Link to post Share on other sites
