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.

See also zero downtime backup (ZDB), ZDB to disk, ZDB to

tape, instant recovery, replica, and replica set rotation.
