What information is in a Data Domain Autosupport?   
    The Autosupport feature generates a report called an ASUP report, also referred to as just “autosupport” by the system.   
    It shows system identification information, consolidated output from a number of Data Domain system commands and recent entries from various log files.   
    The Autosupport is configured to send home to Dell|EMC daily on a user configurable schedule or whenever the file system is started.   
    Alerts are sent immediately when an event is triggered and contain only that specific event information (is not “scheduled”).   
        
    No user “data” or passwords are transmitted within the ASUP file or alerts.   
        
    How is the ASUP sent to Dell|EMC?   
    There are various method to transmit the file back to Dell|EMC;   

         
  1.         Email via customer Email server (traditional)        
               
    1.             This is not an encrypted file, plain text email to Dell|EMC via the customer mailserver.         
    2.        
                  
  2.      
  3.         Email via customer Email server (ConnectEMC)        
               
    1.             This IS an encrypted file sent to Dell|EMC via the customer mailserver.         
    2.        
                  
  4.      
  5.         ESRS connect home via customer ESRS gateway.        
               
    1.             The entire transmission is secured by ESRS itself using HTTPS 'by reply' only.         
    2.        
                  
  6.    
        
    The options available to send home are dependent on whether the customer has ESRS, which version of ESRS and which DDOS code version is operating on the Data Domain.   
        
    Where do the ASUP’s go when they reach Dell|EMC?   
    The ASUP files are stored by Dell|EMC on an internal only basis, customer specific information variables are correlated to the DD serial number within this internal system/installed base rather than from that information being transmitted within the content of the ASUP itself.   
    The ASUP’s can be used to track historical trends or current status for service requests resolution or for making accurate sizing calculations, thus allowing assessments to be made without disturbing the end user.     
     
      For more detailed information, support may request a Support bundle, sometimes called a SUB, this is a larger and more detailed file for deeper analysis, it needs to be manually collected and uploaded to EMC, it will not be sent by the Data Domain like an ASUP or an alert.     
      The content of a SUB is not discussed here.
   
        
    What information is contained within the ASUP?   
        
    This ASUP content will vary based on DDOS version, so includes, but is not limited to;
