RDAREAs under a unit are backed up during operation of a HiRDB/Parallel Server.
The system configuration is shown in Figure 6-3 System configuration example for backup made using JP1/OmniBack II: JP1/OmniBack II handles communications between server machines. The RDAREAs under unit UNT2 in server machine 2 are backed up. The backup is to be stored in a JP1/OmniBack II object in server machine 3.
System log files are swapped in order to physically separate the system logs needed for database restoration. To restore the RDAREAs from the backup copy to be created in step (2), the system log collected subsequently (the system log in the file to be used as the current file after swapping) will be used as input information.
