[Veeam] Failed to index guest file system. Veeam Guest Agent is not started

2

A customer asked me to repair their Veeam Backup & Replication 7.0 backup job, some virtual machines were showing this warning message in the backup log:

Failed to index guest file system. Veeam Guest Agent is not started

 

Solution:

The default Domain Administrator (Veeam Service Account) credentials are not working at the standalone / workgroup virtual machine that is running in the DMZ VLAN.

Note: Make sure the virtual machine has the latest version of VMware Tools installed

To configure specific credentials:

– Edit the backup job

– Navigate to: Guest Processing > click: Advanced

– Select failing virtual machine > Click: Set User

– Configure the local administrator credentials

– Result: the Virtual Machines which are domain joined are using <default> credentials. The Virtual Machine without domain is now using the local Administrator credentials..

 

Final result

  1. Thanks! It may be useful clarification: the account must be in a domain\login form (NOT IN login@domain !!!). In the latter case, the test is successful, but when job starts the error occurs again.

  2. I was struggling with this issue on one of my 12 vms for over 3 weeks. I changed the password to the service account that controlled the backups first, then followed your instructions. Success!! thanks.
