Does Nexus have repository synchronization function

[jibingjie2]

I now have two nexus instances. For some reason, the old nexus may shut down and lose data at any time, so I need a solution for nexus data synchronization. My nexus mainly stores Maven artifacts. I have referred to many articles on the Internet, but there are no available solutions. I want to know if there is a way to manually synchronize data in nexus

My two nexus versions are:
OSS 3.64.0-04
