1.2.11 Offloading of Incremental Backup Processing

To optimize the performance of incremental backups, the database can offload block filtering to Oracle Exadata Storage Server.

This optimization is only possible when taking backups using Oracle Recovery Manager (RMAN). The offload processing is done transparently without user intervention. During offload processing, Oracle Exadata System Software filters out the blocks that are not required for the incremental backup in progress. Therefore, only the blocks that are required for the backup are sent to the database, making backups significantly faster.
