@woe2you @NotYours I second this advice.
Maybe set a reminder in your calendar to do a backup once every 2 weeks, just in case? This is one of the shining features of the Fediverse, you can simply migrate to a new server and bring all your follows and followers with you.
For the highly technical people here, you could even migrate your post archive to a self-hosted GoToSocial instance by using the SLURP tool. But I don't want to overcomplicate things (even I couldn't do it)
