The problem is that you're mixing hardware and software compression.

About 5GB was *successfully* written to tape, consisting of 4 files (Nb 4)

The tape drive hit end of tape just shy of 17GB, which makes sense for a
DDS-4 drive in which both hardware and software compression are being used.
I would strongly recommend shutting off hardware compression on the drive
and readjusting your tapetype to be closer to the 20GB native tape size.
