Photos and videos are thrown into a multi-drive RAID 6 NAS with TB's capacity as the main central storage. RAID 6 offers redundancy against disk failure and easy plug & play replacement. An external USB backup drive attaching to the NAS does incremental backup daily. Periodically the data are snapshot to other USB backup drives and kept off site.

The NAS server has apps that offer backing up to various cloud services, but I choose not to use them.
