Backup to a Remote Disk. 

Use

You can make a backup to a remote disk directly with BRBACKUP/BRARCHIVE, or together with an incremental backup with the Oracle Recovery Manager (RMAN).

Backup to the disk of a remote host only appropriate when the network is very fast and stable. This means that this procedure cannot be recommended for production systems in most cases.

Prerequisites

The following prerequisites must be satisfied for a backup to remote disk:

1.) Specification of the password in the parameter remote_user.

remote_user="<user_name> <password>"

2.) Password is not specified explicitly: In this case, the password of the BRBACKUP database user is used automatically. You must make sure that the password of the operating system user is the same.

Remote Disk Backup with BRBACKUP

The remote backup to disk removes the need for a NFS disk mount, if the backup is to made through the network. The NFS protocol is relatively insecure. This means that the backup must be verified. In contrast, RCP and FTP are relatively secure ways of transferring data over the network. This means that the backup does not have to be verified.

The following entries have to be made in the initialization profile init<DBSID>.sap :

backup_dev_type = stage|stage_copy|stage_standby
stage_copy_cmd = rcp|ftp

A remote backup to disk is particularly useful in connection with the standby database configuration, and support for the AMASS software (Hierarchical Storage Management System of the company EMASS).

Incremental Remote Backup with RMAN

You can use RMAN to make an incremental backup to the disk of a remote host. As well as satisfying the aforementioned prerequisites, you also have to make the following entries in the initialization profile init<DBSID>.sap :

backup_dev_type = stage
backup_mode = incr

FTP is always used automatically as the transmission program.
