Joe - if the 2 compresion processes are both software, the yes, the output of the 2nd compression will be large than its input. But if the 2nd compression is being done by a tape drive, the drive will be smart enough to stop the compression if the file grows. It least that is the case for 3590 & 9840.
I am doing exactly what you are doing and I get 19.2 GB on a 9840, which is the nominal uncompressed capacity.
