2.2.4 Configuration example for disaster recovery operation

For the disaster recovery supported by JP1/AJS3, a system that has the same environment as the system that is operating regularly is set up at a remote site, and the updated contents of the shared disk for the regular system are copied to the shared disk at the remote site. This arrangement allows you to prepare for a large-scale disaster or other unexpected events. Use the disk copy and mirroring functionality of the hardware to copy data between the shared disks.

In JP1/AJS3 disaster recovery, the system that is operating regularly is called the main site, and the system located at a separate remote site is called the remote site.

The following figure shows an example of a system configuration for the disaster recovery supported by JP1/AJS3.

For details about the system configuration or the procedure for performing disaster recovery operation, see 11. Disaster Recovery in JP1/AJS3 in the JP1/Automatic Job Management System 3 Administration Guide.

For details about the disaster recovery setup, see 9. Setup Required for Disaster Recovery Operation in the JP1/Automatic Job Management System 3 Configuration Guide (for Windows) or 18. Setup Required for Disaster Recovery Operation in the JP1/Automatic Job Management System 3 Configuration Guide (for UNIX).

Depending on the method of connection, a LAN connection might be required between the main-site host and remote-site host. Depending on the hardware you use, you might also need to install software before you can use the copy and mirroring functionality between shared disks at the main and the remote sites. For details, see the documentation for the hardware.
