I think I have found the problem. Thanks, Sam.
Hi, When the protection group runs, it ends with the error. If I go to check the Library configured in DPM 2010, I can see the error message for the drive "No Tape Label. Contains no Data" The Firmware is B.20 and BBH4. Any suggestions? Thanks in advance!  Pin
