My boss has asked me to find File replication software that is FREE or something much cheaper than veritas storage replicator. he wants to replicate the data files from server1 to server2 for a disaster recovery plan. both servers are located in the same room. i have found data replicator, IDEM and file replication pro. Have any of you used this software or using similiar software that you would recommend?.

both servers are nt4 servers.
