2.5 Interacting with Veritas NetBackup and Oracle RMAN
3PAR Recovery Manager integrates 3PAR Virtual Copy with Veritas NetBackup (NBU) and
Oracle RMAN to dramatically reduce the performance impact on the database host, as well as
to minimize database down time during backup. Instead of a traditional backup where the
database is backed up directly on the production server, Recovery Manager creates a virtual
copy (snapshot) of the database, imports it to a secondary host (backup host), and then
performs the backup of the virtual copy on the backup host.
Recovery Manager provides two ways to perform backup and restoration: NBU (user-managed)
and Oracle RMAN.
For NBU (user-managed) backup and restoration, Recovery Manager interacts directly with
NBU to trigger the backup/restore process. Recovery Manager requires that the NBU client
must be installed on the primary (database) server and the backup host.
For Oracle RMAN backup, Recovery Manager supports backup to tape and backup to disk. If
Recovery Manager is configured to perform backup to disk, Recovery Manager interacts with
Oracle RMAN to trigger the backup process. If Recovery Manager is configured to perform
backup to tape, Recovery Manager interacts with Oracle RMAN, which in turn interacts with
NBU to trigger the backup/restore process. Recovery Manager requires that Oracle database
software (Oracle RMAN) and Veritas NetBackup Client must be installed on the primary host
and the backup host. Additionally, Veritas NetBackup for Oracle (Oracle Agent) must be
installed on the primary host, backup host, and NetBackup master server, if you select to
backup to tape.
Recovery Manager requires that at least one NBU policy must be created per database.
Optionally, a separate NBU policy can be created for archive log backup (backup archive log
only). The NBU policies must be created as "standard" type or "Oracle" type for NBU (user-
managed) backup/restore or Oracle RMAN backup/restore, respectively (see 4.7 Setting Up
NetBackup Policies for NBU (User-Managed) Backup on page 4.19 or 4.8 Setting Up NetBackup
Policies for Oracle RMAN Backup on page 4.22 for detailed information).
NOTE: For an ASM managed database, Oracle RMAN backup is the only
supported backup method.
