Question for brbackup together with Oracle RMAN

[Former Member]

Hi All,

We have the following environment:

A production SAP server connected to a storage with mirror it.

We will do a full backup by apply split mirror online, and the splited volume

will be mounted by a backup server, with netbackup on it, to do a full backup on it.

And the question is that, after the full backup, whether we can use rman to do the incremental backup instead of full backup?

If yes, any documnet describe about it?

Hi Xentar,

with BR*Tools 7 this is supported.

See note

<a href="http://service.sap.com/sap/support/notes/968507">#968507 - Considerable enhancements to backups using BR*Tools 7.00</a>

for details on it.

Hi

Yes you can do that.

In the case of the following backup types:

backup_type = online_split|online_mirror|offline_split|offline_mirror

the following settings are now valid:

backup_dev_type = rman_util|rman_disk|rman_stage

or

backup_dev_type = tape|tape_auto|tape_box|pipe|pipe_auto|pipe_box

tape_copy_cmd = rman

or

backup_dev_type = disk

disk_copy_cmd = rman

You can even execute full backups (level 0) and incremental backups in this configuration. However, to do this, you must use the sapbackup directories from the database and backup servers together (shared/mounted).

<b>Note:</b> To be able to execute an RMAN backup on the backup server, the BRBACKUP database on the backup server is set to the mount status. For this to happen, the Oracle Server software must be completely installed on the backup server.

Thanks for all answer the question.

I would like to ask more about on the following:

Note: To be able to execute an RMAN backup on the backup server, the BRBACKUP database on the backup server is set to the mount status. For this to happen, the Oracle Server software must be completely installed on the backup server.

As before backup, the production is connected to the SAN disk.

And once during backup, brbackup is trigger to split mirror the SAN disk.

And the Backup server is mounted up with the splited disk and do the full backup of that disk.

After the full backup, the splited disk is attached back to the production SAN disk.

For the next schedule backup, split mirror is occured, and the splited disk is mounted up by the backup server. But how can i to set it to be backup incremental backup with RMAN? As the scn number, or some tables that stored the information about which the data is being full-backup is being over-write after re-mirror the split-disk? And i am kind of confused of the concept of it.

Would anyone provide more information or doc about how to implement of it?
