NetWorker Module - EMC Symmetrix for SAP R/3 on Oracle

NetWorker Module for EMC2 Symmetrix for SAP on Oracle (NMES) delivers live, serverless backup and recovery of SAP R/3 applications on Oracle databases stored on EMC2 Symmetrix Enterprise Storage Systems. Managed by NetWorker, NMES is fully integrated with EMC2 TimeFinder technology and SAP BR*tools to provide automated protection and optimizes application performance. SAP data is copied directly from the Business Continuance Volumes (BCV) to tape using a secondary server, enabling Oracle databases to remain fully accessible and free from the impact of backup operations. With NetWorker Module for EMC2 Symmetrix for SAP on Oracle true 24x7 service level attainment can be realized for even the largest SAP R/3 applications.

Protecting SAP R/3 applications online traditionally relies upon Oracle log files and database server resources. This method works well for small to medium sized SAP R/3 applications that can be backed up during "off-peak" hours when SAP demand is light. However for large SAP R/3 environments that must operate at peak service levels "around-the-clock", impact-free protection is needed to achieve business objectives. NMES delivers live, automated protection without sacrificing SAP R/3 performance.

NMES contains two key components. The first component resides on the Oracle server and upon initiation by NetWorker, places the database in a consistent state utilizing SAP BR*tool commands. Through interaction with EMC2 TimeFinder, this component then splits off a mirrored BCV volume and returns Oracle to its normal state. This takes only seconds and avoids the sluggishness that can occur from filling log files during backups of large, highly active databases.

The second component resides on a secondary server connected to the EMC Symmetrix array and copies the Oracle data from the split BCV volume directly to tape. Since backup traffic bypasses Oracle server resources, administrators can perform full backups including important Oracle control and log files at anytime, without impacting user productivity – eliminating the need for a backup window. Once complete, the mirrored volume is automatically re-synced.

In the event of data loss, NetWorker enables individual data files or an entire database to be readily restored. NMES also fully leverages NetWorker’s backup scheduling, efficient indexing, and advanced media handling, including library and dynamic drive sharing, to keep overhead low and service levels high. These combined features further simplify, centralize and automate SAP information protection, thus reducing overhead and total cost of ownership.
