Keeping player data between updates

Guys, I know that every rust experimental receive news updates and with that I have to update my server too for players that want to log-in.

Sooooo, what can I save between updates in my server?

 

one way would be to recode the copy-paste to save all players buildings, meaning a LOT of data, and probably some fail placing backs as the world some times change (+ the placeback is bugged atm).
you could keep some of your players stuff or your own stuff but an entire server, well some major coding would be required, and just a poor gain, as all servers wipe anyway, so it's not like players can rage quit XD (unless they rage quit rust XD)

 

Last weekend I kept the persistence folder but this week in server log it appears that some players have files that aren't updated
