145Replicator 15The replication command sets up and manages the Data Domain Replicator for replication ofdata between two restorers. The Replicator is a licensed product. Contact Data Domain sales oryour Data Domain SE for license keys. Use the license add command to add one key to eachrestorer in the Replicator pair.A Replicator pair is an originator restorer that receives data from backup servers and a replicarestorer that receives data only from the originator. A restorer can be either an originator or areplica, not both. See “replication” on page 237 for the complete command syntax. Afterreplication initialization, the originator constantly checks the status of the replica.A replica that is removed (with the “break” option on either the originator or replica) from theReplicator pair cannot be brought back into the pair or used as a replica for another originatorunless the file system on the replica is emptied with the filesys destroy command.A replica is a read-only machine for any connection except the originator in the Replicator pair.You can mount a replica as read-only for access from other places; however, after using the “break”option on a replica, the replica itself becomes a read/write machine.All user information, such as user names, passwords, and permission level (administrative or user),is replicated from the originator to the replica. User information on the replica is overwritten. Achange to user information on the originator causes the file to be sent to the replica. A change madeon the replica is lost when changes are next made on the originator.Note The filesys destroy command erases all Replicator configuration settings.Configure ReplicatorTo configure two restorers as a Replicator pair, use the replication set sourceorig-name destination replica-name operation. Administrative users only.• The source orig-name on both the replica and originator must be exactly the same as the namereturned by the hostname command on the originator.• On the originator, the destination replica-name must be a name that can be translated to an IPaddress or be an IP address.
