ZDB to tape	(ZDB specific term) A form of zero downtime backup where
	data in the replica produced is streamed to a backup medium,
	typically tape. Instant recovery is not possible from such a
	backup, so the replica need not be retained on the disk array
	after backup completion. The backed-up data can be restored
	using standard Data Protector restore from tape. On split mirror
	arrays, split mirror restore can also be used.
	See also zero downtime backup (ZDB), ZDB to disk, instant
	recovery, ZDB to disk+tape, and replica.
zero downtime	A backup approach in which data replication techniques,
backup (ZDB)	provided by a disk array, are used to minimize the impact of
	backup operations on an application system. A replica of the
	data to be backed up is created first. All subsequent backup
	operations are performed on the replicated data rather than the
	original data, while the application system can be returned to
	normal operation.
	See also ZDB to disk, ZDB to tape, ZDB to disk+tape, and instant
	recovery.
