Datafile backup - A backup of datafiles only.
•
Archive log backup - A backup of archive logs only.
Recovery Manager for Oracle can be configured to perform either NBU (user-managed) backup
or Oracle RMAN backup.
The Database Backup Utility
HP 3PAR Recovery Manager Software for Oracle’s database backup utility supports full and/or
incremental backup of an Oracle database or archive log destination. Full backup of an Oracle
database or archive log destination are always supported regardless of backup method (NBU
backup or Oracle RMAN backup). However, incremental (differential or cumulative) backup of a
whole Oracle database is only available using Oracle RMAN backup. Incremental (differential or
cumulative) backup of archive log destination is only available for the NBU (user-managed) backup
method.
The following restrictions apply when backing up a database using the Recovery Manager for
Oracle database backup utility.
•
For NBU (user-managed) backup:
The NBU client must be installed on the backup server, as well as on the database server. ◦
◦ At least one NBU policy of standard type must be created and configured for database
backup. Optionally, a separate NBU policy of standard type can be created and
configured for archive log destination backup.
•
For Oracle RMAN backup:
If RMAN sbt_tape backup is chosen, the NBU for Oracle client must be installed on the
backup server, as well as on the database server. ◦
◦ If RMAN sbt_tape backup is chosen, at least one NBU policy of the Oracle type must be
created and configured for database backup. Optionally, a separate NBU policy of the
Oracle type can be created and configured for archive log backup.
◦ An RMAN Recovery Catalog database must be created and configured prior to using
the backup utility.
There are two ways to perform backups:
•
Immediate backup - a backup that is initiated by Recovery Manager for Oracle through the
database backup utility.
•
Automatic backup - a backup that is initiated by NBU from the NBU master server.
Immediate Backup
During an immediate backup, Recovery Manager for Oracle performs the following:
•
Creates an online, offline, datafile, or archonly Virtual Copy for the database or archive log
destination.
•
Mounts the Virtual Copy on the backup server.
For NBU (user-managed) backup, Recovery Manager for Oracle:
•
Generates an include list file that contains a list of datafiles and/or archive log destination
on the mounted Virtual Copy and stores it in the
/usr/openv/netbackup/include_list.<policy_name>
file on the NBU client (the
backup server).
•
Calls the bpbackup command from the NBU master server to backup files listed in the include
list.
