How to store media files if the application is running on multiple servers?

Question

Django

What is the best way to store upload files when the application is running on multiple servers?
Ideally on s3, probably. But in this case, it doesn't really suit me, it's better to just store the files locally. But how to make it so that if a user uploads a file on 1 server, it is also available on all the others?
Surely this question is solved relatively simply, but 15 minutes of googling did not bring me closer to the answer :(

Any distributed storage, mongo, redis, memcached, ceph...
