# ELO Replication
ELO Replication compares entries between multiple repositories. The relevant repositories can be installed at different sites. ELO Replication transfers the data to the relevant repositories. This means the repositories do not necessarily have to be available to one another.
This documentation covers the following topics:
- basics such as functionality, terms, and concepts
- Installing ELO Replication
- Setting up and editing a replication
- Operating ELO Replication
- Monitoring the status of an active replication
