    Set
用法
Dim instance As Backup
Dim value As Boolean

value = instance.Initialize

instance.Initialize = value

public bool Initialize { get; set; }

public:
property bool Initialize {
    bool get ();
    void set (bool value);
}

member Initialize : bool with get, set

function get Initialize () : boolean
function set Initialize (value : boolean)

属性值

类型：System. . :: . .Boolean
A Boolean value that specifies whether the backup devices will be initialized.
If True, the backup specified becomes the first backup set on the media, overwriting any existing backup sets on the media. The backup media is not overwritten if either of the following conditions is met:

  • All backup sets on the media have not yet expired.

  • The optionally specified backup set name does not match the name on the backup media. Specify the backup set name with the BackupSetName property.

If False (default), the backup specified creates a new backup set appended as the last backup set on the medium.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")
Dim bk As New Backup
bk.Action = BackupActionType.Database
bk.Database = "AdventureWorks2008R2"
bk.Initialize = true

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2008R2")
$bk = new-object Microsoft.SqlServer.Management.Smo.Backup
$bk.Action = [Microsoft.SqlServer.Management.Smo.BackupActionType]::Database
$bk.Database = "AdventureWorks2008R2"
$bk.Initialize = $TRUE
