属性值
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.

Dim bk As New Backup
bk.Action = BackupActionType.Database
bk.Database = "AdventureWorks2012"
