 Failed to index guest file system. Failed to zip folder

I have a different error- Failed to index guest file system. Failed to zip folder 'c:\users\.....Appdata\Local\Temp\GuestIndexData.zip. 

I am seeing the below warning on backup jobs. We have VEM installed so cannot disable Guest indexing. Backup will complete successfully with this warnings. Using Domain admin account for Guest processing and indexing. 

Warning :Failed to index guest file system. Failed to zip folder 'C:\Users\tn\AppData\Local\Temp\66ddcb73-b3b1-4fea-8333-ffa67ef9aace' to file 'C:\Users\tn\AppData\Local\Temp\66ddcb73-b3b1-4fea-8333-ffa67ef9aace\GuestIndexData.zip'VBRCatalog is saved in C: drive and have 386 GB free of 599 GB

VBR 12.1 version VEM 12.1

r/Veeam - Failed to index guest file system. Failed to zip folder 'c:\users\.....Appdata\Local\Temp\GuestIndexData.zip

 

Please advise.

Hello 🙂

 

My first guess if this is across multiple VMs is your anti-virus software is locking the zip file as it’s being created to scan it, so check your AV exclusions.

Confirmed AV is not blocking

No luck. I changed to local proxy from automatic , still same issue. This is happening to only a set of vms, others are working with same configuration with automatic proxy.

Any one know what is this Illegal characters in path error means?

Unsure what the illegal character is in the error as the path does not seem to have an illegal character.  I might suggest at this point to contact Support for further assistance as they will be able to dive deeper in to the log files to assist.  Keep us posted.
