Información de backups

El siguiente script tiene por objetivo entregarnos toda la información correspondiente a los respaldos realizados sobre todas las bases de datos de una instancia. En el mismo se encuentra un filtro que nos permite saber la información de un día exacto. Dicho script ha sido probado exitosamente desde la versión SQL Server 2000 hasta 2014
