This article documents how to locate and gather the VSS and VIX log files for troubleshooting investigation.


While investigating an issue related to Application Aware Processing or Indexing additional logs must be gathered manually from the Guest OS for the VM that is failing to backup.

These logs are NOT automatically captured by the Support Wizard, they must be manually collected.


Note: If Application-Aware Image Processing was disabled during internal troubleshooting please enable Application-Aware Image Processing and run the job again to update the log files within the Guest OS.

Collecting logs from within Guest OS

The following actions are to be performed within the Guest OS of the VM that is being investigated. Please note that no Veeam Backup and Replication task should be running against the guest in question during this collection process. This will interfere with the accuracy of the information.


  1. Navigate to the following directory %programdata%\Veeam\Backup User-added image
  2. Collect files matching the following Syntax:
    • VeeamGuestHelper_ddmmyyyy
    • VeeamVixProxy_ddmmyy
  3. Open an elevated command prompt and run the following commands:
    vssadmin list writers > C:\vsswriters.txt vssadmin list providers > C:\vssproviders.txt vssadmin list shadows > C:\vssshadows.txt vssadmin list shadowstorage > C:\vssshadowstorage.txt
