NetWorker Module for EMC2 Symmetrix for Oracle (NMEO) delivers live, serverless backup and recovery of Oracle databases stored on EMC2 Symmetrix Enterprise Storage Systems. Managed by NetWorker, NMEO is fully integrated with EMC2 TimeFinder, SRDF technology, and Oracle to provide automated protection and optimizes database performance. Oracle data is copied from a Business Continuance Volume (BCV) or Symmetrix Remote Data Facility (SRDF) Volume directly 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 Oracle, true 24x7 service level attainment can be realized for even the largest Oracle databases.

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

NMEO 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 Oracle’s “alter tablespace” function. Through interaction with EMC2 TimeFinder or SRDF, this component then splits off a mirrored BCV or SRDF 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 or SRDF 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. NMEO 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 Oracle information protection, thus reducing overhead and total cost of ownership.
