ZDB part of the IDB (ZDB specific term)

A part of the IDB, storing ZDB related information such as original and replica storage versions, security information and other. The ZDB part of the IDB is used for ZDB, instant recovery, and split mirror restore.

See also zero downtime backup (ZDB).

ZDB tape backup (ZDB specific term) The basic concept of ZDB tape backup is to create a copy of data from the original storage at a specific point-in- time, and use this copy of data in the replica storage version for a backup to a standard backup medium, typically a tape. After the backup is complete, the data in the replica storage version may be overwritten. Instant recovery is not possible from such a backup, the data must be restored following the standard Data Protector restore procedure.

zero downtime backup (ZDB)

A backup process utilizing data replication technologies (the split mirror and snapshot technologies) to minimize the backup window for the application system; typically to few minutes. With this technique, application database downtime (offline backup) or backup

mode (online backup) is limited to the very short time it takes to split the mirror disks or to create or reuse snapshots. The application is then returned to normal operation, while the data in the replica storage version is either backed up by streaming the data to tape (ZDB tape backup) or kept in the replica storage pool (ZDB disk backup) for the instant recovery or other purposes or both (ZDB disk/tape backup).
