6Using NSR-ORA with NetApp Filers

This chapter describes how to configure and use NSR-ORA with NetApp Filers

6.1Running NSR-ORA with NAS devices

NSR-ORA allows database files stored on a Network Attached Storage (NAS) you to be backed up or recover or recovered using NDMP (Network Data Management Protocol). The data is written and read directly from the NAS device to the backup media, so the performance of the database computer is not degraded during the backup process. The NetWorker server controls the tape drives, labeling and initiates tape changers to provide tape media. The database itself is managed (start, stop, set to “Backup Mode”) by NSR-ORA on the database computer.

Currently, NSR-ORA only works together with the NAS devices from NetworkAppliance®(NetApp), called NetApp Filers. Fujitsu Siemens Computers will provide support for other systems in future.

As a special feature of NSR-ORA using NetApp Filers the software supports the NetApp Snapshot feature. A NetApp Snapshot is a snapshot of the database at the moment the NetApp Snapshot is created. This snapshot file will not be changed even though the database is still operating and its data is being contin- uously. Due to NetApp’s specific working method the snapshots are created in a very short time and generally request only a small amount of storage. Therefore several snapshots can be held on a NetApp Filer.

The integration of NetApp snapshots provides the following benefits:

Using a Snap-Restore(Restore of a snapshot) can considerably reduce the time needed for a recovery operation.

Using NetApp snapshots allows the administrator to back up the database more often. This reduces the time needed for recovering a database after a logical error has occurred, because the number of redo logs to be re- adjusted will be smaller.

An online backup of the database takes only a few minutes (from the database server’s point of view). Since the database in a consistent state is already stored on a snapshot a following tape backup of the data is completely independent of the backup itself.
