SQLBackupAndFTP creates standard *.bak files when it runs locally on the same computer where SQL Server is. For remote SQL Server computer backups SQLBackupAndFTP creates backup script files (*.sql). Whenever possible, you should always opt for *.bak backups against *.sql backup files.
Here we will show you how to backup a SQL Server on the network to the standard *.bak file even when SQLBackupAndFTP runs on a different computer from where the SQL Server is. The main requirement, in this case, is that both SQL server and SQLBackupAndFTP have access to the same shared network folder.
