Hi, Its on you device class definitions. Device Class Name: LTO_PRIM Device Type: LTO Format: DRIVE You can change the default from "drive" to ultrium 4c for forced compression. This will only help if you data is not already compressed (being compressed data by nature like .jpg/zip etc or due to host based compression).
