Tableau Server backup fails with the error below when running data engine backup estimation. 

Error - Caused by: java.nio.file.NoSuchFileException: E:\Tableau\Tableau Server\data\tabsvc\dataengine\ToFetchFolderIds. 

  • tsm.log reported there is disk space issue even though there is enough disk space on the Tableau Server.
  • Backup usually fails at EstimateRequireSpace failed around 2 minutes time.
  • Run as user account and network service account has the full permission on Tableau Server folder.


  • Tableau Server 2019.4.6, 2020.2.8


Option 1

Upgrade to Tableau Server 2020.2.12, 2020.3.7, and 2020.4.3

Option 2
  • Re-run the backup
  • Use '--override-disk-space-check' option to skip the disk check


This is a known issue that is fixed in more recent versions Tableau Server.  The root cause is a failure to estimate the data engine backup size due to a file missing when walking the file tree.
