You can balance disk usage using split_clients module in nginx, and use different proxy_cache’s (e.g. /disk1/cache, /disk2/cache and so on) as described in https://www.nginx.com/blog/nginx-caching-guide/ (Splitting the cache across multiple hard drives).

The NGINX-proxy, which added them there in the first place, can serve the content correctly, after skipping the right amount of metadata bytes. In my case, I have a background application, which might copy the cached file to an alternate location. For example, a file movies/welcome.mp4 may be originally cached by NGINX-proxyon /disk1/cache as /disk1/cache/movies/welcome.mp4 (For the moment, let us forget the md5-based cache path for simplicity). In my use-case, the file may either stay there itself, or sometimes, my application may copy it to another location - say /disk2/cache/movies/welcome.mp4 or say, /disk3/cache/movies/welcome.mp4, say for some kind of disk usage balancing.. The application exposes /disk1/pubroot/cache/movies/welcome.mp4 as the published location. In this model, only the originally cached file at /disk1/cache can be served properly by the NGINX-proxy. The files in any of the other locations cannot be served by NGINX properly. It cannot serve as a server, as the copied file contains metadata. Even if I have other proxy-cache-paths defined for the alternate locations (/disk2/cache or /disk3/cache), the NGINX-proxy also cannot serve them as the corresponding in-memory metadata will not have the entries for these files. The files in those paths, would have been physically copied "under the hood" by another process, and not NGINX.
