DESCRIPTION
Recovery Manager integrates 3PAR Virtual Copy feature with Veritas NetBackup(NBU) and
Oracle RMAN to perform off-host backup. Off-host backup can dramatically reduce
performance impact on the database host as well as minimize database down time or the time
database in backup mode during backup.
The first form of vcdba_backup command initiates an immediate backup of an existing
database virtual copy. The virtual copy must have Available status (not mounted) in order to
be backed up. The vcdba_backup command mounts the virtual copy to the backup host
before initiating an immediate backup (off-host).
The second form of vcdba_backup command creates a new database virtual copy, mounts it
to the backup host before initiating an immediate backup (off-host). If the database being
snapshot is a physical standby database and Oracle release is not 11g, the Oracle parameter file
and control file of the production database must be backed up manually in addition to the
virtual copy. This is because the parameter file and control file are not compatible between the
standby and production database.
Recovery Manager supports NBU (user-managed) backup and Oracle RMAN back-up methods,
which can be specified during the Recovery Manager configuration process. If Oracle RMAN is
used for backup, the primary (not standby) database must be registered with the Oracle
Recovery Catalog Database. For the Oracle RMAN backup method, you can select the SBT_TAPE
or DISK option to backup to tape or disk, respectively. Starting with Oracle 11g, an RMAN
backup image of a standby database to local disk cannot be seen from the Recovery Catalog
from the production database. Therefore, the backup image cannot be restored to the
production database using the vcdba_restore command. Please see the vcdba_restore
command man page on how to perform restore manually. Regardless of backup method,
Recovery Manager supports full backup of an Oracle database or archive log destination.
