NSR-ORA and NetApp

NSR-ORA needs two or three NetWorker pools for NDMP backups:

●

One pool is required for the backup of database tablespace files. This 
pool must be usable on the NDMP drive. 

   These pools must also be available for normal (non-NDMP) 

drives. When starting a database backup and during the backup 
of log- and Oracle files the relevant pool is also required by the 
NetWorker server or storage node.

●

One or two pools are required for the backup of archive redo log files, 
depending on whether the redolog files are backed up only once or twice 
(mirror backup). 

To backup redolog files a separate client with the name of the database host 
is neccessary. However you do not need to create one if a client already 
exists for this host. 

For each of the pools mentioned above, NSR-ORA needs a separate label 
template.

The following section gives information about controlling the backup process 
and the errors which may occur.

There are two parameters which determine the method NSR-ORA uses for a 
backup:

●

:

With this parameter set to “full” a snapshot is created and afterwards NSR-
ORA starts a backup on a NetWorker medium using the nsrndmp_save 
command.
