Resolution

Follow the steps below to verify that the Run As Service Account of Tableau Server has the necessary folder permissions.

1. Get the location of the current export file and check if it actually exists. For more information see Get the current file location.
tsm configuration get -k basefilepath.site_export.exports

2. Confirm the Run As Service Account. For more information see Change the Run As Service Account.
tsm configuration get -k service.runas.username

3. Verify that the Run As Service Account has granted permissions to the location of the current export file as follows, then try tsm sites export again.
The below example is by default,

Run As Service Account: NT AUTHORITY\NetworkService
The export location: C:\ProgramData\Tableau\Tableau Server\data\tabsvc\files\siteexports

Cause

In some complex deployment scenarios, you may need to verify or manually configuration the Run As service account permissions on the local Tableau Server computer.
