If you plan to back up your Vault data to a remote share, you must create a new domain user account, create a remote share, and set the new account in the Autodesk Data Management Server Console.
After these steps are complete, modify the SQL Service to use a domain account using the following steps.
In the Control Panel, Administrative Tools, double-click the Services icon.
Double-click the SQL Server (autodeskvault) service, and select the Log On tab.
Select the This Account radio button, and enter a domain account in the form of Domain_Name\Domain_account (with-the-correct-password).
Verify that the account specified has write access on the share to which you are backing up.
