Tomando una copia de seguridad de la base de datos desde otro servidor Estoy tratando de restaurar a sqlexpress en el host local. Esta restauración funcionará a través de la interfaz gráfica de usuario, pero estoy teniendo problemas para restaurarla con PowerShell. Me sale el siguiente mensaje de error:Error al restaurar la copia de seguridad de la base de datos a la nueva base de datos con smo y powershell
