Backup di dati mediante la deduplicazione globale

Global deduplication finds redundancies between C:\ drive backup sessions on different machines being backed up to the same deduplication device. Generally, the C:\ drive of a given machine holds operating system files, where high instances of redundancy are expected. Oltre ai volumi di sistema, la deduplicazione globale gestisce anche sessioni RMAN Oracle.

Global Deduplication happens every 6 hours but cannot happen while a backup or purge job is active, and will be interrupted if both jobs need to access the same session file.

To perform global deduplication, set up a backup job in the usual manner, ensure you have checked the Enable Global Deduplication option in Deduplication Device Group Configuration and you have select the C:\ drives of different machines specified as the backup source.
