Last night I started a new backup job. The job was successfull. I checked
the tape itself and the data (16GB) appears to be all there, but the log
reports that it only backed up 1GB, however the verify reports that it verified
all 16GB.

I've searched through the knowledge base and found an article that describes
the same sort of mismatch when software compression is used. I'm using hardware
compression though. Can anyone explain this? below is a cut and paste of
the log.

Thanks in advance.
