About library-based cleaning
NetBackup does not support library-based cleaning for most robots because robotic library and operating systems vendors implement this cleaning in different ways. (Library-based cleaning also is known as robotic cleaning or auto cleaning.) These different methods often interfere with NetBackup robotic control operations.
NetBackup does not define the cleaning media that is used for library-based cleaning, and the robotic library manages the cleaning media.
Because TapeAlert provides the same type of cleaning as library-based cleaning, Veritas recommends disabling library-based cleaning when you use TapeAlert.
