[MCU] Does Tony have backups of his AIs?

After JARVIS is integrated into Vision, we never see it again, and FRIDAY takes it's place. Does Tony not have a backup of JARVIS, or even all his AIs somewhere in his computer/cloud? 

Or is that not the case as we see Tony revives JARVIS only after he retrieves it's protocols in the Nexus?

Jarvis was designed to be able to learn and grow and adapt. Tony wrote the basic programme, switched him on, and then stepped back and let Jarvis develop his personality from there.

Tony could in theory boot up a new Jarvis, but it wouldn't be the same. And given that he treats Jarvis almost as a friend, he probably wouldn't *want* to do that.
