The i5/OS™ Save and Restore CL commands support directly-attached optical media library devices, CD-ROM, DVD-ROM, and DVD-RAM stand-alone devices.
The best use of optical storage devices is as a part of disaster recovery protection. The extraordinary long shelf life of optical media is well suited for the long term storage of critical data. You can provide extra protection by using permanent WORM media because you cannot alter data on the media. Tape devices may provide the optimal day-to-day backup mechanism. This depends on the amount of data that you want backed up, and the amount of system time available for backup. CD-ROM and DVD-RAM media are also well suited for software distribution. The save/restore command interface can be used as a part of installation procedures for programs, data, and program fixes. CD-ROM and DVD-RAM stand-alone drive optical devices also support the Load Run (LODRUN CL) command.
