public bool CopyOnly { get; set; }

Property Value

Type: System.Boolean

A Boolean value that specifies whether the backup is a copy-only backup.

If True, the backup is a copy-only backup.

If False (default), the backup is not a copy-only backup, and is part of the usual sequence of backups.

A copy-only backup does not affect your overall backup and restore procedures for the database.

Copy-only backups were introduced in SQL Server 2005 for use in situations in which a backup is taken for a special purpose, such as backing up the log before an online file restore. Typically, a copy-only log backup is used one time and then deleted.
