Question

有没有办法调用Backup-SqlDatabase cmdlet，但是它是否使用SQL Server凭据连接到SQL Server 2012？

我目前使用的命令是：

Backup-SqlDatabase -ServerInstance $serverName -Database $sqldbname -BackupFile "$($backupFolder)$($dbname)_db_$($addinionToName).bak"

但这取决于正在调用它的用户，默认情况下，正在使用Windows身份验证。

Answer 1

backup-sqldatabase cmdlet支持Credential参数。如果查看cmdlet的帮助，甚至还有一个示例（来自help backup-sqldatabase -full）：

 -------------------------- EXAMPLE 4 --------------------------

 C:\PS>Backup-SqlDatabase -ServerInstance Computer\Instance -Database MyDB -Credential (Get-Credential sa)


 Description
 -----------
 This command creates a complete database backup of the database 'MyDB', using the sa SQL Server credential. This co
 mmand will prompt you for a password to complete SQL Server authentication.

Answer 2

在运行Backup-SqlDatabase

之前，你可以connect a virtual drive

$backupFolder = '...'
$additionToName = '...'

$user = 'Username'
$pass = 'Password'
$inst = 'Server\Instance'
$db   = 'master'
$file = "$backupFolder${db}_db_$additionToName.bak"
$root = "SQLSERVER:\SQL\$inst"
$drv  = 'sqldrive'

$cred = New-Object Management.Automation.PSCredential -ArgumentList $user, $pass

New-PSDrive $drv -PSProvider SqlServer -Root $root -Credential $cred -Scope 1
Set-Location $drv
Backup-SqlDatabase -ServerInstance $inst -Database $db -BackupFile $file

或者您可以通过SQL statement运行Invoke-SqlCmd来备份数据库：

$backupFolder = '...'
$additionToName = '...'

$user = 'Username'
$pass = ConvertTo-SecureString 'Password' -AsPlainText -Force
$inst = 'Server\Instance'
$db   = 'master'
$file = "$backupFolder${db}_db_$additionToName.bak"

$sql = @"
USE $db;
GO
BACKUP DATABASE $db TO DISK = '$file';
GO
"@

Invoke-Sqlcmd -Query $sql -ServerInstance $inst –Username $user –Password $pass

将Backup-SqlDatabase cmdlet与SQL Server身份验证配合使用
