Content Replication Pattern

Content Replication is a Sonatype Nexus Repository Pro feature that allows you to publish artifacts in one Sonatype Nexus Repository instance and then have another instance pre-emptively fetch via HTTP to provide faster artifact availability across distributed teams. This is different from (and faster than) Federated Repositories or Bi-Directional Proxying where a proxy repository must fetch content on demand. 

Combines With 

Problems Addressed

  • Fast, low-latency content availability across geographies
  • No timeouts for large file access


  • Sonatype Nexus Repository Pro
  • Both instances must be using a PostgreSQL database
  • Both source and target instance must use same Sonatype Nexus Repository version
  • High-bandwidth network
  • Selectivity about which repositories to proactively replicate

Factors to Consider

  • Consumes significant bandwidth
  • Not appropriate for disaster recovery
  • Content replication requires that the source repository be a hosted repository and the target be a proxy repository
