Hello Curtis_Meadow,
We recommend using a local folder as the temporary directory, but you can also try specifying a network path to a NAS starting with two slashes as the temporary folder.
However, it is essential that when using Windows authentication, the user also has write access to this network directory. Alternatively, if SQL Server authentication is used, both the user running the SQLBackupAndFTP (Database Backup) Windows Service and the user running SQL Server must have access to this directory.
Please let us know if you have any other questions.
Thank you for choosing SQLBackupAndFTP.
