Each backup set on media, including foreign backup sets such as Microsoft® Windows NT® file backups, is numbered. This allows the backup set you want to restore to be referenced easily. For example, the following media contains four backup sets: two Microsoft SQL Server™ backups and two foreign backup sets (Windows NT files).
To restore a specific backup set, specify the position number of the backup set you want to restore. For example, to restore the second SQL Server backup set, the fourth backup set on the media, specify 4 as the backup set to restore.
