If tape is used instead of disk, the tape for the synthetic image must be different from the tape where the component images reside.

The maximum drive usage applies only to the drive that is needed for writing the synthetic backup. If any of the component images reside on tape, an additional drive is needed for reading.

If a single tape drive device is used to generate synthetic images, place component images in a hard drive location first. In that way, a synthetic image can be generated with the single tape drive device.
