How to organize data synchronization between static servers?

Question

Highload

There is static from the servers, when there is not enough bandwidth - we start a new instance.
Now there is a certain central server - any changes in statics are uploaded to it. On the rest of the servers, there is an rsync cron - which picks up from the "central" update.
In general, the solution works, but I don’t like that there is about a minute of time when the data versions may differ on the servers.
What are the best approaches to solve this problem?

You can run rsync on servers with a script, something like: ssh server1 rsync coreserver ./ &
