Question

我正在尝试备份SQL Server 2008 R2数据库，数据库名称为test。

我正在使用以下PowerShell脚本，但是我收到一条错误消息，指出数据库不存在，但我可以看到test数据库和表，我可以查询它。

Backup-SqlDatabase -ServerInstance testpc-001\SQLEXPRESS -Database test -BackupAction   
Database

如果我尝试使用

编辑上述脚本

$date = Get-Date -Format yyyyMMddHHmmss
$dbname = 'test'
Backup-SqlDatabase -ServerInstance SQLEXPRESS -Database $dbname -BackupFile   
"C:\DBbackups\$($dbname)_db_$($dt).bak"

我收到错误，无法连接到SQLEXPRESS

Answer 1

$date = Get-Date -Format yyyyMMddHHmmss
$dbname = 'test'
Backup-SqlDatabase -ServerInstance testpc-001\SQLEXPRESS  -Database $dbname -BackupFile   
"C:\DBbackups\$($dbname)_db_$($date).bak"

-ServerInstance参数

中存在拼写错误

Answer 2

$datetime = (Get-Date).ToString('MM-dd-yyyy');
$database1 = "Path\to\folder" + $datetime + ".bak";

$password = ConvertTo-SecureString "password" -AsPlainText -Force
$Cred = New-Object System.Management.Automation.PSCredential ("password", $password)

Backup-SqlDatabase -ServerInstance "SERVER ADDRESS" -Credential $Cred -Database Dummy_Bkp -Initialize -BackupFile $database1;

start-sleep -Seconds 20
