Orphaned data and objects are those that have not been sent to the backup system when a production system failure occurs.
You can prevent orphaned data by ensuring that there are no jobs other than MIMIX currently active on the source system. To ensure this, you may need to end all interactive and batch subsystems other than those associated with MIMIX. You should also prevent your users from accessing either system until after the switch is complete and the data group is restarted.
MIMIX provides journal analysis tools for user journal replication processes that can be used after an unplanned switch to identify any orphaned data.
