Yosemite Server Backup 8.7.01 and newer
Error 4458 in Yosemite Server Backup is meant to inform the user that though the device is an HP tape device, the hardware reported that it does not support HP?s One-Button Disaster Recovery (OBDR) solution. As such, the user will need to use the ?Make Bootable CD-DVD? task available to create a separate boot media to be able to perform disaster recovery from this tape.
The full text of the error 4458 is:
The media could not be prepared for boot with HP's One-Button Disaster Recovery (OBDR) solution. The boot track was not written to the media since the selected tape device is not capable of being used as a boot device with HP's One-Button Disaster Recovery (OBDR) solution. If you want to use Disaster Recovery with this media, a separate boot media must be created with the Disaster Recovery Wizard.
