-  * A server is a tracker responsible for all the videos uploaded on it.

-# Redundancy
-
-A PeerTube instance can cache other PeerTube videos to improve bandwidth of popular videos or small instances.
-
-## How it works
-
-The instance administrator can choose between multiple redundancy strategies (cache trending videos or recently uploaded videos etc), set their maximum size and the minimum duplication lifetime.
-Then, they choose the instances they want to cache in `Manage follows -> Following` admin table.
-
-<p align="center">
-
-<img src="user/redundancy.png" alt="Redundancy" />
-
-</p>
-
-Videos are kept in the cache for at least `min_lifetime`, and then evicted when the cache is full.
-
-When PeerTube chooses a video to duplicate, it imports all the resolution files (to avoid consistency issues) using their magnet URI and put them in the `storage.videos` directory.
-Then it sends a `Create -> CacheFile` ActivityPub message to other federated instances. This new instance is injected as [WebSeed](https://github.com/Chocobozzz/PeerTube/blob/develop/FAQ.md#what-is-webseed) in the magnet URI by instances that received this ActivityPub message.
-
