XBSA interface
(Informix Server specific term) ON-Bar and Data Protector
communicate with each other through the X/Open Backup
Services Application Programmer's Interface (XBSA).
XCopy engine
(direct backup specific term) A SCSI-3 copy command that allows
you to copy data from a storage device having a SCSI source
address to a backup device having a SCSI destination address,
thus enabling direct backup. The data flows from a source device
(either block or streaming, that is, disk or tape) to the destination
device (either block or streaming) through XCopy. This releases
the controlling server of reading the data from the storage device
into memory and then writing the information to the destination
device.

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.
