    As you are planning an audit of your long term retention data using the IBM Spectrum Protect Audit Volume command, it's important to remember that the Audit Volume command can check for damaged files as well as check for data integrity. In other words, detect logical inconsistencies in the data.

    Solution:

    Based on our experience using IBM Spectrum Protect, we have gathered best practices related to data integrity from different knowledge sources. One step that is frequently missed is the enabling of the CRCData feature for each Storage Pool before the data is backed up. This is important; otherwise, it will not validate the integrity of the data nor detect logical inconsistencies.

    Command information  from the IBM knowledge center:

                   

    Syntax:

    DEFine STGpoolpool_namedevice_class_name POoltype=ACTIVEdata
    CRCData = Yes
                        No

    CRCData enabled to Yes: Specifies that data is stored containing CRC information, allowing for audit volume processing to validate storage pool data. This mode impacts performance because more processing is required to calculate and compare CRC values between the storage pool and the server.
