Backup methods

Schedule a backup of an existing Oracle backup specification using the Data
Protector Scheduler. See

Scheduling backup specifications

” on page 81.

Start an interactive backup of an existing Oracle backup specification using the
Data Protector GUI or the Data Protector CLI. See

Running an interactive

backup

” on page 82.

Start a backup on the Oracle server using either Oracle Recovery Manager or
Oracle Enterprise Manager. See

Starting Oracle backup using

RMAN

” on page 85.

Backup procedure

The following happens when you start a backup using the Data Protector user
interface:

1.

Data Protector executes ob2rman.pl on the client. This command starts RMAN
and sends the Oracle RMAN Backup Command Script to the standard input of
the RMAN command.

2.

The Oracle RMAN contacts the Oracle Server, which contacts Data Protector
via the MML interface and initiates a backup.

3.

During the backup session, the Oracle Server reads data from the disk and sends
it to Data Protector for writing to the backup device.

Messages from the Data Protector backup session and messages generated by
Oracle are logged to the Data Protector database.

A backup of the Oracle recovery catalog is performed automatically following each
Oracle target database backup, unless otherwise specified in the backup specification.
Using the standard Oracle export utility, the Data Protector ob2rman.pl starts an
export of the Oracle recovery catalog to a file which is then backed up by Data
Protector.

Deleting data from the recovery catalog

When backing up an Oracle database using the recovery catalog database, all
information about the backup, restore, and database recovery is stored in the recovery
catalog. This information is used by RMAN during the restore. If you overwrite or
format the media on which this data is backed up, Data Protector exports the object
from the Data Protector database. You must manually delete the data from the recovery
catalog while logged on to RMAN. See the Oracle Recovery Manager User’s Guide
and References
for detailed information about deleting data from the recovery catalog.
