    Did you see this?

    The job has been configured for either data encryption or software compression, or both. 
    The job is also targeted to a device that is capable of data deduplication. 
    Encryption and compression of the backup data can prevent much of the data from being deduplicated.

        The job log tells me that the job has completed  (there are similar stats for databases and System state): 

        Backed up 125219 files in 3623 directories.
Processed 13,010,471,599 bytes in  13 minutes and  38 seconds.
Throughput rate: 910 MB/min
Compression Type: Software
Software compression ratio: 2:1

         

        but with VERY low dedupe rate (5.7%)  :

        Deduplication Stats::PDDO Stats for (BACKUP-SRV1): scanned: 176983320 KB, CR sent: 166825813 KB, 
        CR sent over FC: 0 KB, dedup: 5.7%, cache hits: 92228 (5.4%)

         

        The 'exception' is a warning to tell you about about it. 

        You should not enable compression on a job that goes to dedupe storage. 
        See BE Admin Guide for details.
        You are wasting your dedupe storage and will fill it up way too soon.
