NSR-ORA and NetApp

This section provides recommendations for using NSR-ORA to backup data on 
high performance NAS devices.

1. For the Archivelog files backup (Amon backups) and to save the backup infor-

mation a second, non-NDMP device is required. This device should be 
connected to the database server. However it is also possible to use another 
remote volume, that does not work with the NDMP protocol and in this case 
the data is backed up over the network.

2. It is strongly recommended that the NetApp volumes be arranged as follows:

–

For every database to backup you should use exactly one volume

–

On the relevant volume the database should be exclusively stored (this 
rule may be broken when backing up the control and the online redolog 
files which can be located on another remote and/or local volume).

Otherwise performing a snap restore operation may fail.

3. Do not store all of the control files on the NetApp volume. At least one of 

them should be located on a local drive.

4. The online redo log files may be mirrored by ORACLE. It is recommended 

that the original online redolog files should be stored on the database’s 
NetApp volume and the mirrored files on the database’s local drives.

This section describes the configuration of NSR-ORA when used with a NetApp 
Filer.

When running the configure_nsrora script the administrator will be asked if the 
database is located on an NDMP Filer. If “yes” the administrator will be prompted 
to setup the following parameters:
