Restauração do banco de dados SQL com um novo nome
Para restaurar um banco de dados com um novo nome, talvez seja necessário deslocar os arquivos do banco de dados em disco. Vai depender se o banco de dados original ainda estiver presente.
Se o banco de dados original não estiver mais disponível, o parâmetro where ou o “Plugin Options” pode conter o novo nome do banco de dados, e o plugin tratará automaticamente da criação com o novo nome.
Se o banco de dados original ainda for necessário, o parâmetro where deve ser usado para realocar os arquivos em disco, e o novo nome do banco de dados deve ser definido com o menu “Plugin Options”. O layout.dat deve ser selecionado na árvore de restauração.

Restauração do SQL para disco local
Ao especificar where=c:/path/, os arquivos serão restaurados para o sistema de arquivos local e o administrador MS SQL poderá usar um TSQL ou o Console de Gerenciamento do Microsoft SQL Server para restaurar o banco de dados. Os comandos SQL necessários para fazer isso são impressos na saída da tarefa, como mostra o próximo exemplo.
* 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
Automatically selected Client: win2008-fd

You are now entering file selection mode where you add (mark) and
remove (unmark) files to be restored. No files are initially added, unless
you used the “all” keyword on the command line.
Enter “done” to leave this mode.

Restauração do banco de dados “master”
As instruções sobre como restaurar o banco de dados “master” estão detalhadas neste artigo: https://technet.microsoft.com/en-us/library/aa213839%28v=sql.80%29.aspx
Banco de dados em estado de restauração
No final de uma restauração, se a plugin option de recuperação foi definida para no, o banco de dados restaurado ficará estado de “restauração”. Para terminar o processo, a recuperação precisa ser executada. Isso pode ser feito com o seguinte comando SQL:
RESTORE [yourdatabase] WITH RECOVERY;
