I had this same issue. Using the link above, I determined my local system account was not given the âsysadminâ role in SQL. Iâm guessing this may be because I have an SQL Express version installed, and not a full version installed. Hope this helps you. Once I gave NT Authority\System the role of sysadmin, Duplicati works great.
I have the same issue that is yet to be resolved. itâs puzzling , because I have another computer with the same setup using Duplicati as a service and I do not receive this error. When adding a backup job, I get âFailed to enumerate Microsoft SQL Server databases: Microsoft SQL Server VSS Writer not found - cannot backup SQL databases.â SQL Server VSS Writer is running and set as Automatic and Duplicati is running as well. I have even tried setting theDuplicati service to logon as the Administrator account, but itâs still not working.
Any help would be much appreciated.
One thing, when I first installed Duplicati as a User, there was no error message, but after adding it as a service I get this pop up. I am running Duplicati 2.0.4.5_beta_2018-11-28
I think I may have figured out what the issue could be. I have Duplicati completing a similar backup on another server with the same settings. However, apparently the SQL Database version for the software we are using is different so it allows Windows Authentication. That backup using Duplicati as a service has no errors. The current one I am working on however has the SQL VSS writer error when Duplicati is running as a service. When I have it installed as an application which appears in the tray, there is no VSS Writer Error, but there are errors FileEnumerationProcess-FileAccessError when trying to backup Shared Server folders for Users. That error appears to disappear if I right click the Duplicati icon and run the application as an administrator when starting it.
I am trying to find a happy medium to solve all the errors.
