Problem
In Backup Exec 2012 it may be observed that the compression ratio is 1.0:1 or 1:1 when compression is turned on for the backup jobs targeted to tape. Upon further inspection of the tapes it is found that compression IS working correctly even though the Backup Exec UI reports a 1:1 ratio.
To confirm that compression is working correctly please use Tracer.exe as described in the following technote: TECH50960
