ZDB to disk (ZDB specific term) A form of zero downtime backup where the
replica produced is kept on the disk array as a backup of the
source volumes at a specific point in time. Multiple replicas,
produced using the same backup specification at different times,
can be kept in a replica set. A replica from ZDB to disk can be
restored using the instant recovery process.

ZDB to disk+tape (ZDB specific term) A form of zero downtime backup where the
replica produced is kept on the disk array as a backup of the
source volumes at a specific point in time, in the same way as
with ZDB to disk. However, data in the replica is also streamed
to a backup medium, as with ZDB to tape. If this backup method
is used, data backed up in the same session can be restored
using the instant recovery process, the standard Data Protector
restore from tape, or on split mirror arrays, split mirror restore.

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.

zero downtime
backup (ZDB) A backup approach in which data replication techniques,
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.
