How NetBackup decides how much data write on tapes
Please help to understand how NetBackup decides how much data write on tapes. I have created a new backup policy. It creates two copies with differents retention levels, let say 15 and 16. All data...
tapes can have bad spots found at the factory and so formatted in - tapes can later develop bad spots which the tape drive has to then handle and mark/record on the mini-RFID chip inside each tape cartridge - tapes can actually be of different lengths internally (from the factory) - the streaming rate can affect tape writing, i.e. the tape drive may insert many "IRG" (inter record gap) if the data receive rate at the tape head cannot keep up with the tape winding speed.
