2 Hitachi Data Systems WebTech Educational Seminar Series Simplifying Online Backup Operations for Microsoft Exchange, SQL and Oracle with Hitachi Protection Manager Software Business Session: Microsoft Exchange, SQL and Oracle databases are critical business applications for most IT environments. Additionally, these environments have complex SAN and backup solutions. The tasks associated with discrete management of these business applications to maintain complete defined time images are both complex and involved. Hear from Craig Chan, Software Product Manger how Hitachi Protection Manager software uses its application awareness to backup these applications to be successfully recoverable., You ll learn how to: Simplify complex tasks associated with database storage operations with Hitachi Replication Manager Centrally manage database volume, backup target and device, as well as automate restoration operations Use the Correlation Wizard to generate ad hoc reports Use new functionality available in application aware storage solutions and gain an understanding of what this means to your Microsoft Exchange, SQL and Oracle operational and data protection needs 2

3 Data Protection Protecting data is THE key element is Business Continuity and Disaster Recovery planning. Some risk examples are Data Corruption Hardware or Software Failures Major Data Center Disaster Viruses Most large enterprises, especially those in the financial sector deploy several different technologies, not only to recover data but also to minimize data loss 3

7 Hitachi Protection Manager Introduction Hitachi Protection Manager is a Split-Mirror backup solution Discovers SQL/Exchange and File system objects and maps the relationship from databases of instance to storage LUNs Works with VSS for Exchange and NTFS Works with VDI for SQL Hitachi Storage replication product is pre-requisite Currently supports Exchange 2000, 2003 and 2007 SQL 2000 and 2005 SharePoint 2007 Oracle Supports all Hitachi Storage Subsystems Hitachi Universal Storage Platform family Hitachi Adaptable Modular Storage family Legacy Hitachi storage systems Lightning, Thunder Typical Use Case Disk-to-Disk-to-Tape Backup 7

8 Hitachi Protection Manager for Oracle Overview What s New on Hitachi Protection Manager version 6.1? Now supports Oracle 10g, 11g database on Solaris 9, 10 (SPARC) environment Provides a Solaris edition of Hitachi Protection Manager Copy Controller" and "Hitachi Protection Manager for Oracle" What is Hitachi Protection Manager for Oracle? Allows user to perform high speed and simplified backup and restore operations Utilizes storage volume copy for high speed operation Allows to specify oracle objects (database, tablespace, redo log) instead of volume structure like LDEV, for simplified operation Allows user to manage backup catalog Maintains the backup history, and allows to view and verify the backed up objects Allows user to perform unified backup operation across multiple DBMS Provides similar command architectures among SQL Server, Exchange and Oracle, allowing to reduce the operational cost 8

9 Hitachi Protection Manager for Oracle Overview Quick Look Interacts with Oracle and CCI, to manage mapping between oracle files and physical volumes Oracle Instance Oracle Database Oracle Files Volumes volume copy operation using CCI (Shadow Image, COW Snapshot, etc) HPtM System Tablespace User Tablespace.dbf file 11/2 2:00 AM do rotation 11/1 2:00 AM.dbf file Archived Redo Log.arc file dictionary map file PFILE, SPFILE Control File Online Redo Log.ora file.ctl file (*1) (*2).log file (*3) 9 (*1) HPtM backups files to the folder specified by drmorainit command (*2) If it is cold backup and files are stored on P-VOL, they are backed up to S-VOL. For other case, HPtM backups files to the folder specified by drmorainit command (*3) They are backed up only when cold backup. Backed up from P-VOL to S-VOL.

24 Understanding Hitachi Protection Manager Usage - Restore and Recovery Restore using Hitachi Protection Manager for Oracle Restore using drmorarestore command restore oracle files This command stops the Oracle instance. But, in case all of the following conditions are satisfied, only the restoring tablespaces are placed offline and instance itself is not stopped Restoring a backup acquired with online backup Non-clustered configuration Any of (SYSTEM, UNDO, TEMP) are not included in restore target Specify the backup to be restored by its Backup ID (ex ) PROMPT> drmorarestore resync KAVX0001-I The drmorarestore command will now start. KAVX0019-I Copying file(s) now... KAVX0002-I The drmorarestore command will now end. PROMPT> 24

25 Understanding Hitachi Protection Manager Usage - Restore and Recovery Recovery using RMAN/SQL*Plus Perform the recovery operation using RMAN/SQL*Plus (recovery operation not supported as Hitachi Protection Manager commands) Apply the recovery commands provided by Oracle Start the Oracle instance/online tablespace It is required because drmorarestore command does not start the stopped oracle instance, and does not online the offline tablespaces Example on SQL*Plus PROMPT> sqlplus user/pass as sysdba SQL> startup mount SQL> recover database SQL> alter database open resetlogs; 25

26 Understanding Hitachi Protection Manager Usage - Restore and Recovery Recovery using RMAN/SQL*Plus Oracle provides Roll-Forward recovery and Point-In-Time recovery after restoring the data by Hitachi Protection Manager Tablespace BACKUP : Archived Redo LOGs RMAN run { set until time 12-may-06 15:30 ; } recover database; P-VOL S-VOL BACKUP Recovery Point TIME RMAN> run { drmorarestore 26 } recover database; Roll-Forward recovery using redo log
