23.3.3. Configure Cross-Datacentre Replication Programmatically

The programmatic method to configure cross-datacentre replication in JBoss Data Grid is as follows: 
ConfigurationBuilder lon = new ConfigurationBuilder();
lon.sites().addBackup()
      .site("NYC")
      .backupFailurePolicy(BackupFailurePolicy.WARN)
      .strategy(BackupConfiguration.BackupStrategy.SYNC)
      .replicationTimeout(12000)
      .sites().addInUseBackupSite("NYC")
    .sites().addBackup()
      .site("SFO")
      .backupFailurePolicy(BackupFailurePolicy.IGNORE)
      .strategy(BackupConfiguration.BackupStrategy.ASYNC)
      .sites().addInUseBackupSite("SFO")
Copy to Clipboard Toggle word wrap
The configuration uses the same three site example mentioned previously (where NYC and SFO are backup sites for local site LON).
Next, to programmatically configure which sites NYC and SFO are backups for, use the following: 
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.sites().backupFor().remoteCache("users").remoteSite("LON");
