While we want mastodon.site to be the best choice for hosting a no-hassle mastodon server, we also believe in data portability and that if you want to take your social media elsewhere we’re here to help.
Mastodon also stores some data in a temporary cache (Redis). Some of this is genuinely cache data and doesn’t need migrating anyway; some of it is used to store the current timeline of users (and some in-flight queue data).Unfortunately we have no way to export this for you, but once you start up a new server this cache data will start to populate again.
