Web Help Desk down: The transaction log for database 'WHD' is full due to LOG_BACKUP

Updated September 29, 2016


This article shows how to resolve the issue where WHD down and TRUNCATE EMAIL_DATA_OBJECT gives the following error message:

 The transaction log for database 'WHD' is full due to 'LOG_BACKUP'


  • WHD 12.2.3
  • Windows Server 2012


This occurs when EMAIL_DATA_OBJECT size increases exponentially.


Address the database issue

  1. Change Database Recovery model from Full to Simple.
  2. Shrink log files using SQL Studio.
    1. Right click WHD Database > Tasks > Shrink > Files.
    2. Select Log in File Type field.
    3. Click on OK.
  3. 3. Truncate EMAIL_DATA_OBJECT.


Control the growth of EMAIL_DATA_OBJECT,

  1. Log in to the WHD Console as an Administrator
  2. Go to Setup > E-Mail > Options.
  3. Under E-Mail Options, look for Delete E-Mail History Entries After and set it to a shorter period.
  4. Save.

Note: The EMAIL_DATA_OBJECT table mainly stores data for reference, such as when an email is rejected.
