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.
For Oracle RMAN backup, Recovery Manager for Oracle:
•
Starts up a clone database in mounted mode using the mounted virtual copy on the backup
server, assuming ORACLE_HOME is installed and configured in the Recovery Manager
repository.
•
Calls an RMAN backup script (rmora_rman_dbbackup.sh or
rmora_rman_archbackup.sh
) to backup the cloned database.
•
Removes the cloned database.
•
Unmounts the virtual copy.
