How newsfeed work and how to backup newsfeed content?

Question

I am using Sharepoint 2013 standard (on-premise) and I am wondering how to backup the conversion content within newsfeed.
Is there any good article explain how newsfeed I/O? Is there any OOB or 3rd party solution to backup the content?
Finally, I think newsfeed content is stored in cache. May I know how long the cahce will be kept?
Thanks for any input. Maybe my search skill is bad. I have tried and fail to find a good source explain newsfeed mechanism.

Hi Mark,
According to your description, my understanding is that you want to know how the Newsfeed works in SharePoint and how to back up the Newsfeed content.
As you said, SharePoint 2013 makes use of distributed cache to cache newsfeeds, microblogging, conversations, security trimming, OneNote client access, and even keeps the FedAuth cookie for claims based authentication on the server side.
All Activities are written to the Distributed Cache. The microblog features and feeds rely on the Distributed Cache to store data for very fast retrieval across all entities. Feeds mainly Rely on the following two Caches from Distributed Cache service: Feed
Cache and Last Modified Time Cache.
If the activity is a user activity or site activity, the activity is saved to the My Sites content database; If the activity is a site feed activity, the activity is saved in the team sites content database. Tags and document activities are not saved to
content databases. So individual My Site Newsfeed backup is not supported OOB, custom solution needs to be performed for getting My Site Newsfeed from feed cache.
