Description:
Challenge
This KB provides troubleshooting advice for investigating an apparent Exchange log truncation issue.
Cause
Exchange truncation may not occur for the following reasons: The Backup Job is not configured to trigger truncation. The VSS operation occurring during the job is not notifying the Exchange VSS writer that a backup has occurred. The Exchange VSS writer is receiving notification that a backup has occurred, but an issue within the Exchange software prevents truncation.
Solution
Confirm Truncation Is Enabled Within the Backup Job Application-Aware Processing must be enabled to cause a Veeam Backup Job to trigger Exchange log truncation. Confirm this by editing the job, going to the Guest Processing tab, and ensuring the Enable application-aware processing is checked. In addition to ensuring Application-Aware Processing is enabled, check that truncation is enabled for the Exchange server. Click the [ Applications... ] button, then in the window that opens, highlight the Exchange server and click [ Edit ]. Within the processing setting window, make sure that the job is set to either "Require successful processing (recommended)" or "Try application processing, but ignore failures," then make certain "Process transaction logs with this job (recommended)" is selected.
