Caché performs logical replication while traditional ( OS- / SAN- / Disk-based ) replication technologies perform physical data replication.
Logical data replication mitigates the risks of physical replication such as carry-forward corruption ( where corrupt sectors from one storage media are replicated to the other storage media ).
In addition, Caché synchronizes the least amount of data necessary, thereby optimizing the amount of network bandwidth required between the two systems.

Bei der logischen Datenreplikation werden die Risiken der physischen Replikation wie der Übertrag von Schäden ( die Replikation beschädigter Sektoren von einem Speichermedium auf das andere ) gemindert.
Darüber hinaus synchronisiert Caché die geringstmögliche Datenmenge.
