Backup And Restore Types - HP Data Protector A.06.11 Integration Manual

• The tablespaces are in backup mode (online backup) or the database is shut
down (offline backup) only during the short period required to create a replica
(split the mirror disks or create snapshots).
• The load to the application system is significantly reduced. Following the replica
creation, tape backup can be started on the copied data, at leisure, using a
separate backup system.
The Data Protector Oracle ZDB integration offers online and offline backup of your
Oracle Server System (application system).
The online backup concept is widely used since it enables high application availability.
Offline backup requires shutting down the database while creating a replica, and
therefore does not offer high availability.
ZDB methods and Oracle versions
The installation, upgrade, configuration, and parts of backup flow are different
depending on the selected Oracle ZDB method. These differences are indicated
where appropriate.
The procedures for configuration of backup specifications and starting or scheduling
backups are the same, regardless of the Oracle ZDB method.

Backup and restore types

Backup
Using Data Protector, you can perform the following types of backup:
• Online ZDB to disk, ZDB to tape, and ZDB to disk+tape.
During the creation of a replica, the database on the application system is in hot
backup mode. If a ZDB-to-tape or a ZDB-to-disk+tape session is being performed,
the streaming of the data to tape media is subsequently performed on the backup
system.
• Offline ZDB to disk, ZDB to tape, and ZDB to disk+tape.
During the creation of a replica, the database is shut down on the application
system. Therefore, the database is not available during the short time that it takes
to create the replica. If a ZDB-to-tape or a ZDB-to-disk+tape session is being
performed, the streaming of the data to tape media is subsequently performed
on the backup system.
With both online and offline ZDB to tape or ZDB to disk+tape, a standard Data
Protector (non-ZDB) backup of the recovery catalog and the control file is started
