You can set automatic archive and deletion of archive settings to permanently remove content from Hub.
Hub does not set a limit size or time-related to content for archived content.
*It is best to not automate these processes in case you need to republish archived content and to turn on automation with the intention to clean out the archives then turn off the automation to ensure that content is not automatically removed by the system.
