9.3 IBM System Storage FlashCopy Manager
IBM has two optional offerings that are compatible with the storage system FlashCopy
function. Each one helps you to easily produce concurrent and consistent copies of your data:
򐂰 IBM Tivoli FlashCopy Manager
򐂰 IBM System z FlashCopy Manager
9.3.1 IBM Tivoli Storage FlashCopy Manager
IBM Tivoli Storage FlashCopy Manager is designed to work in a distributed environment.
It helps deliver the highest levels of protection for mission critical IBMDB2, SAP, Oracle,
Microsoft Exchange, and Microsoft Structured Query Language (SQL) server applications
using integrated, application-aware snapshot backup and restore capabilities. This is
achieved through the exploitation of advanced IBM storage hardware snapshot technology to
create a high performance, low impact application data protection solution.
The snapshots captured by Tivoli Storage FlashCopy Manager can be retained as backups
on local disk. Additionally, with the optional integration with Tivoli Storage Manager, you can
make use of the full range of advanced data protection and data reduction capabilities. These
include data deduplication, progressive incremental backup, HSM, and centrally managed
policy-based administration.
Because a snapshot operation typically takes much less time than does a tape backup, the
window of time during which the application must be aware of the backup is reduced. This
facilitates more frequent backups, which can reduce the time spent performing forward
recovery through transaction logs, increases the flexibility of backup scheduling, and eases
administration.
Application availability is also significantly improved due to the reduction of the load on the
production servers. Tivoli Storage FlashCopy Manager exploits storage snapshot capabilities
to provide high speed, low impact, application-integrated backup and restore functionality for
the supported applications and storage environments. Automated, policy-based management
of multiple snapshot backup versions, together with a simple and guided installation and
configuration process, provide an easy to use and quick to deploy data protection solution
that enables the most stringent database recovery time requirements to be met.

9.3.2 FlashCopy Manager (FCM) support
FlashCopy Manager (FCM) exploits disk subsystems such as these:
򐂰 DS8000
򐂰 SAN Volume Controller
򐂰 XIV system
򐂰 DS 3/4/5k through VSS only
FCM supports applications such as these:
򐂰 Microsoft Exchange 2003 and 2007 on Windows 2003 and Windows 2008
򐂰 Microsoft SQL Server 2005 and 2008 on Windows 2003 and Windows 2008
򐂰 Oracle 10g and11g on AIX 5.3 and 6.1
򐂰 DB2 UDB V9.5 or later on AIX 5.3 and 6.1
Chapter 9. Backup and recovery 169
򐂰 SAP releases running on DB2 V9.5 supported by SAP BRTools 7.10 or later on AIX 5.3
and 6.1
򐂰 SAP with Oracle
Prior to FCM, Tivoli Storage Manager for Advanced Copy Services was the typical solution
used to minimize the back-up window (reducing the time when the systems were offline to
guarantee data consistency for the back-up operation).
Figure 9-7 shows the basic operation of the Tivoli Storage FlashCopy Manager.
Figure 9-7 Basic operations of IBM Tivoli Storage Manager for Advanced Copy Services
With Tivoli Storage Manager for Advanced Copy Services, you can perform these tasks:
򐂰 Trigger a snapshot for backup and map the local snapshot versions to a TSM server
򐂰 Transfer outboard of the application server to minimize impact to the application
򐂰 Provide long-term retention and disaster recovery with copies on the TSM server
򐂰 Provide very fast restore times from the snapshot
򐂰 Provide support for multiple, persistent snapshots
򐂰 Provide persistent snapshots retained locally
򐂰 Provide policy-based management of local, persistent snapshots
򐂰 Have differing retention policies for local snapshots and copies on the TSM server
򐂰 Automatically reuse local snapshot storage when older snapshot versions expire
򐂰 Perform restores:
From local snapshot versions
From TSM storage hierarchy
In addition to these benefits, for certain environments (such as DB2, SAP, Oracle on AIX,
Exchange and SQL on Windows), it is also possible to trigger the snapshot for backup and for
restore, and to exploit the IBM storage subsystem, without the intervention of the TSM Server,
as shown in Figure 8.
