RMAN: Creating and restoring backups on both disk and tape
Last updated on DECEMBER 21, 2016
Applies to:Oracle Database - Enterprise Edition - Version 10.2.0.1 to 18.104.22.168 [Release 10.2 to 11.2]
Information in this document applies to any platform.
It is not possible to backup a database to both disk and tape simultaneously.
You can however backup to disk first and then make a copy of the disk backup to tape using backup backupset command. This can be done in a single RUN block, using pre-configured channels of both types and requires only ONE scan of the database to disk first. The disk backupset is then copied to tape.
The backup and restore can be parallelised on both device types for efficiency and as the initial backup is done to disk, unused block compression is used.
