XCopy engine | (direct backup specific term) A |
| 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 | |
ZDB database | (ZDB specific term) A part of the IDB, storing ZDB related |
| information such as source volumes, replicas and security |
| information. The ZDB database is used for ZDB, instant recovery, |
| and split mirror restore. |

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. |
