they use a CDN which means there's many copies of each video for local server in each country/region to deliver it faster locally.
i do think that is only for the more popular/recent videos. so if those videos are ever lost the server just fetches it from another regional server.
as for their 'low priority' videos id imagine they only appear on youtube servers once but ive never heard of them losing a video so i'd imagine there's an automated backup system like for every X drives there's a backup drive with a XOR of them so if one fails they can rebuild the data on it automatically.
