The main idea is:Use the local data replication function to add a copy of datas on the recovery site to test the DR function without disturbing DR system running;Use the function of storage-based data replication to check the logic error of main site database;Make double data copis on the recovery site and use them with particular policy to avoid database logic error or human factors misoperate,etc; Compile Unix shell programs to automatic manage and control the process of data replication.
