Issue/Introduction
A backup Job is using twice as much space on a tape as it should which is causing jobs to often use more tapes than predicted.
The problem is not related to compression as uncompressed data returns similar statistics - for example approximately 7GB of uncompressed data backed up in an Overwrite job with compression disabled to a tape reports that 15Gb has been used.
