regardless of the backup type (full or incremental), is selected and controlled by
Oracle.
Oracle incremental backups can be differential or cumulative. By default, Data
Protector performs Oracle differential incremental backups. By changing the default
RMAN script created by Data Protector, you can specify also a cumulative backup.
For information on differential and cumulative Oracle backups, see the Oracle
Recovery Manager User’s Guide.
NOTE:
Regardless of the Oracle backup type specified, Data Protector always marks the Oracle
backups as full in the Data Protector database, since the Data Protector incremental
backup concept is different from the Oracle incremental backup concept.
A backup that includes all datafiles and current control file that belong to an Oracle
Server instance is known as a whole database backup.
These features can be used for online or offline backup of the Oracle target database.
However, you must ensure that the backup objects (such as tablespaces) are switched
into the appropriate state before and after a backup session. For online backup, the
database instance must operate in the ARCHIVELOG mode; whereas for offline
backup, objects need to be prepared for backup using the Pre-exec and
Post-exec
options in the backup specification.
The Data Protector backup specification contains information about backup options,
commands for RMAN, Pre- and Post-exec commands, media, and devices.
The Data Protector backup specification allows you to configure a backup and then
use the same specification several times. Furthermore, scheduled backups can only
be performed using a backup specification.
Backup and restore of an Oracle target database can be performed using the Data
Protector User Interface, the RMAN utility, or the Oracle Enterprise Manager utility.
The heart of the Data Protector Oracle integration is MML, which enables an Oracle
server process to issue commands to Data Protector for backing up or restoring parts
or all of the Oracle target database files. The main purpose is to control direct
interaction with media and devices.
Backup flow
A Data Protector scheduled or interactive backup is triggered by the Data Protector
Backup Session Manager, which reads the backup specification and starts the
ob2rman.pl
command on the Oracle Server under the operating system user account
