Esempi

The following code example demonstrates how to create a backup of the AdventureWorks2008R2 database and verify that it is readable and complete.

VB

Dim srv As Server = New Server("(local)")
Dim res As Restore = New Restore()
Dim backup As Backup = New Backup()

backup.Devices.AddDevice("C:\AdventureWorks2008R2Backup.bak", DeviceType.File)
backup.Database = "AdventureWorks2008R2"
backup.SqlBackup(srv)

res.Devices.AddDevice("C:\AdventureWorks2008R2Backup.bak", DeviceType.File)
res.Database = "AdventureWorks2008R2"
Console.WriteLine(res.SqlVerify(srv, true, "The verification has failed.").ToString())

Powershell

$srv = new-object Microsoft.SqlServer.Management.Smo.Server("(local)")
$res = new-object Microsoft.SqlServer.Management.Smo.Restore
$backup = new-object Microsoft.SqlServer.Management.Smo.Backup

$backup.Devices.AddDevice("C:\AdventureWorks2008R2Backup.bak", [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
$backup.Database = "AdventureWorks2008R2"
$backup.SqlBackup($srv)

$res.Devices.AddDevice("C:\AdventureWorks2008R2Backup.bak", [Microsoft.SqlServer.Management.Smo.DeviceType]::File)
Write-Host $res.SqlVerify($srv, $TRUE, [ref]"The verification has failed.")
