NetBackup reports the rate of deduplication as follows:

• The Deduplication Rate column of the Activity Monitor Jobs tab.

• The Job Details dialog box.

  The Detailed Status tab shows detailed information, including the deduplication rate.

  The information depends on whether it is media server deduplication or client-side deduplication, as follows:

  • For media server deduplication, the Detailed Status tab shows the deduplication rate on the server that performed the deduplication. The following job details excerpt shows details for a client for which Server_A deduplicated the data (the dedup field shows the deduplication rate):

    10/6/2010 10:02:09 AM - Info Server_A(pid=30695) 
      StorageServer=PureDisk:Server_A; Report=PDDO Stats 
      for (Server_A):   scanned: 30126998 KB, stream rate: 
      162.54 MB/sec, CR sent: 1720293 KB, dedup: 94.3%, cache 
      hits: 214717 (94.0%)

    The other fields that show deduplication information are highlighted in the example. For the field descriptions, see Table: Deduplication activity field descriptions.

  • For client-side deduplication jobs, the Detailed Status tab shows two deduplication rates. The first deduplication rate is always for the client data. The second duplication rate is for the disk image header and True Image Restore information (if applicable). That information is always deduplicated on a server; typically, deduplication rates for that information are zero or very low. The following job details example excerpt shows the two rates:

• The bpdbjobs command shows the deduplication rate if you configure a COLDREFS entry for DEDUPRATIO in the bp.conf file on the media server on which you run the command.
