Restaurar la base de datos SQL con un nuevo nombre
Para restaurar una base de datos con un nuevo nombre, puede ser necesario reubicar los archivos de la base de datos en el disco. Depende de si la base de datos original todavía está presente.
Si la base de datos original ya no está disponible, el parámetro where o la base de datos «Opciones del plugin» puede contener el nuevo nombre de la base de datos, y el plugin se encargará automáticamente de la creación de la base de datos con el nuevo nombre.
Si la base de datos original sigue siendo necesaria, el parámetro where se utiliza para reubicar los archivos en el disco, y el nuevo nombre de la base de datos debe establecerse con el menú «Opciones del plugin» con la opción de base de datos. El layout.dat debe ser seleccionado en el árbol de restauración.

Restaurar SQL al disco local
Al especificar where=c:/ruta/, los archivos se restaurarán en el sistema de archivos local y el administrador de MS SQL puede utilizar un TSQL o la consola de gestión de Microsoft SQL Server para restaurar la base de datos. Los comandos SQL necesarios para restaurar la base de datos se imprimen en la salida del trabajo como se muestra en el siguiente ejemplo.
* restore where=c:/tmp
First you select one or more JobIds that contain files
to be restored. You will be presented several methods
of specifying the JobIds. Then you will be allowed to
select which files from those JobIds are to be restored.
To select the JobIds, you have the following choices:
1: List last 20 Jobs run
2: List Jobs where a given File is saved
3: Enter list of comma separated JobIds to select
4: Enter SQL list command
5: Select the most recent backup for a client
6: Select backup for a client before a specified time
7: Enter a list of files to restore
8: Enter a list of files to restore before a specified time
9: Find the JobIds of the most recent backup for a client
10: Find the JobIds for a backup for a client before a specified time
11: Enter a list of directories to restore for found JobIds
12: Select full restore to a specified Job date
13: Cancel
Select item: (1-13): 5

Restaurar la base de datos «maestra»
Las instrucciones sobre cómo restaurar la base de datos «maestra» se detallan en este artículo: https://technet.microsoft.com/en-us/library/aa213839%28v=sql.80%29.aspx
Base de datos en estado de restauración
Al final de una restauración, si la opción de recuperación del plugin se estableció como no, la base de datos restaurada estará en el estado «restaurando». Para finalizar el proceso de restauración, debe ejecutarse el proceso de recuperación. Se puede hacer con el siguiente comando SQL:
RESTORE [yourdatabase] WITH RECOVERY;
