How to take backup of nginx cache folder along with metadata?

July 8Hits:2
Advertisement

I want to take a backup of nginx cache folder ( the proxy_cache_path ) and its metadata of the main server and use that as the cache folder of a secondary server. This is so that if the main server goes down the secondary server can take its place and serve the cached urls.

Is it possible to do this ?

I know where the cached files are located and I can copy them, but I think its useless without the metadata associated with it.

Help please ?
