Javik 0 Posted February 12, 2016 Well speaking in general server technology concepts, there are two forms of reliability. One is against storage drive failure, and the other is against power failure. Drive hardware failure protection is called RAID. One or more extra hard drives are used which don't store anything but provide protection in case another fails. Basic: RAID-1 or RAID-5 Good: RAID-1 + hotspare or RAID-5 + hotspare Better: RAID-6 Best: RAID-6 + hotspare Power failure protection usually involves a UPS and a communication cable between the UPS and the protected device: - When the UPS detects a power failure, the protected device continues to run on battery power from the UPS. - The device is informed by the UPS of the power failure. The device starts a controlled shutdown process so that data is not corrupted or lost. - The UPS goes into "sleep mode" to conserve battery capacity after the device turns off. - When power is restored, the UPS wakes up and powers up the protected device. This is a standard protection method against power failure for full-blown computers running a Windows operating system. However, I don't know if any of the custom all-in-one standalone DVR boxes that can also do this. It's not easy to find this information, due to the reseller rebranding BS that muddles and confuses the surveillance industry. Share this post Link to post Share on other sites
