Smaller size tape volumes may transfer quicker to the cloud because transfers can start when a tape volume is unloaded from the virtual drive. This means when a tape volume spans, the cloud transfer of the full volume can start before the backup completes.
When using smaller tape volume sizes, there are reporting limitations in BRMS if more than 50 volumes are used for the backup. If more the 50 volumes are used, the Media_Set_Info table function may be used to return the serial media set information.
Optical volume transfers do not start until the backup completes.
The size may be adjusted slightly to reflect minimum or maximum size of the virtual media.
This will not affect the sizes of optical media when BRMS creates virtual optical media for control groups QCLDBIPLxx and QCLDBGRPxx . For these, the images will be created with *DVD4700 to enable them to be burnt to physical DVD unless the Cloud NFS Solution is enabled.
