I am able to import the media into Robotic Library Slot. However, when I start running test backup for this backup server with OS Win2012, I am receiving this error.
Is there anything wrong with my configuration/setting or wrong media type?
Do you multiple generations/types of tape drives in your library? If not, please turn off bar code rules in the BE properties page of the tape library.
What tape library and tape drive are you using? Those bar codes do not look like typical LTO bar codes.
