Random verify failures but the GUI is reporting success

Last night SQL Backup reported two verify failures. The GUI is reporting that the files successfully verified.

Random failures I understand - I'm running Windows, but telling me that something succeeded when it in fact failed is extremely troubling.

Can we get this fixed? It is really, really important to know when a verify job failed.




Here is one example:

  • Same thing happened with one of our backups this morning....
    At least the MAILTO_ONERROR worked and we got notified. But the GUI showing all is well isn't so great.

  • Hi,
    If possible, could you perform the following query on the instance that created the backup:
    master..sqbdata 'SELECT * from backuphistory 
      WHERE dbname = ''&lt;db_name&gt;'' AND backup_start &gt; ''2007-09-27'' 
      AND backup_start &lt; ''2007-09-28'' ';
    

    This communicates with the server components internal data store, and should return one or more rows of data which relate to the backups performed during this timeframe (adjust the dates as necessary).

    For the row that relates to the failed backup, could you copy the entire row, and paste it into an email and send it to me at [email protected] please? Of particular interest is the values "verified", "code" and "sqlerrorcode" - which relate to the backup state and verification state respectively.

    Thanks,
    Jason
  • The query returned 0 rows.

  • Hi DBA_Dave,
    In your case, you'll need to use the following (the 27th - 28th date range was for the other David):
    master..sqbdata 'SELECT * from backuphistory
      WHERE dbname = ''&lt;db_name&gt;'' AND backup_start &gt; ''2007-09-25''
      AND backup_start &lt; ''2007-09-26'' '; 
    

    What I'm interested in is the values of "verified", "code" and "sqlerrorcode" for the backup in question, since they are what determine to the SQL Backup GUI whether it was verified or not.

    Thanks,
    Jason
