1. Crie no banco Master a seguinte STP

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 |

2. Crie em txt o comando a ser executado, podendo ser
Exemplo1: BKP full de todos os bancos usando a autenticação do windows
sqlcmd -S .\EXPRESS –E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’, @backupType=’F'”
Exemplo2: BKP Diferencial de todos os bancos, usando o sql login
sqlcmd -U SQLLogin -P password -S .\SQLEXPRESS -Q “EXEC sp_BackupDatabases @backupLocation =’D:\SQLBackups’, @BackupType=’D'”
Exemplo3: BKP dos logs de todos os bancos, usando autenticação do windows
sqlcmd -S .\SQLEXPRESS -E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’,@backupType=’L'”
Exemplo4: BKP Full de banco chamado USERDB com autenticação windows
sqlcmd -S .\SQLEXPRESS -E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’, @databaseName=’USERDB’, @backupType=’F'”
Salva o arquivo como .Bat
3. Agora você deve agendar o arquivo .bat criado no gerenciador de tarefas
- Vá em All Programs>Accessories>System Tools>Scheduled Tasks.
- Abrak Add Scheduled Task.
- Em scheduled Task Wizard, clique em Next.
- Em browser, escolha o .bat criado.
- Tipo SQLBACKUP para o nome da tarfa, escolha a periodicidade e clique em Next.
- Especifique a informação de agendadamento da tarefa. Next.
- user namee/pass digite suas credenciais. *de preferencia coloque o adm do sistema
- Clique em Finish.
- Execute para testar
Note A pasta para o SQLCMD executavel é geralmente (C:\Program Files\Microsoft SQL Server\90\Tools\Binn).
