2 Consolidate your backup systems to save money and reduce risks Contents 2 Introduction 2 Customer scenario: Backup and restore consolidation project 9 Implement your project with Tivoli Storage Manager 11 Transform and consolidate with IBM Tivoli 11 For more information Introduction With data continuing to grow at alarming rates and IT environments continuing to become more distributed and complex, the strains and costs of providing data protection and recovery capabilities are getting the attention of many executives. Gartner estimates that by 2014, at least 30 percent of organizations will have changed backup vendors due to frustration over cost, complexity or capability. 1 Adding to this complexity, most companies have on average more than two backup software solutions deployed, as indicated in a recent survey by Storage magazine. 2 And many organizations utilize a considerably larger number of backup tools, as they have expanded to new countries, acquired new subsidiaries, deployed new platforms and applications, expanded protection to remote offices and employee workstations, and come under new regulatory or governance mandates. While some organizations justify adding a specific type of backup tool to meet each new challenge, complexity and costs often increase with each new tool. This issue raises the question: When a data disaster occurs, are you confident that the right person with the right training will log into the right system, restore the right data to the right place, do it in a timely manner and not make anything else worse in the process? As the complexity of your environment grows, so does the likelihood of your answer to that question being no. Since you may have already consolidated your servers, your storage and your networks, it is probably time to consider consolidating your backup and restore systems onto a single, scalable, cost-effective unified recovery management platform. Customer scenario: Backup and restore consolidation project Demonstrating the potential benefits and cost savings of this backup consolidation strategy, the approach taken by one multi-national utility company provides a prime example. This company has been geographically expanding and acquiring regional utilities for several years, with each new acquisition presenting an entirely different IT environment with different rules governing each entity. It quickly became obvious that this distributed and independent model of IT management was costing the company millions of dollars, and the data protection and recovery systems were

IBM Software 3 assumed to be a major contributor of excessive costs. But the company could not prove with certainty that this was the case no single person had more than a narrow window into the overall environment. To begin assessing its infrastructure and looking for potential solutions, the company decided to turn to IBM Global Technology Services. The company s management and IT staff already knew they had 22 distinct data centers, but they only had a rough estimate of the hardware and software deployed and used in each data center for backup and recovery. IBM understood that approaching this challenge with a manual question-and-answer style analysis would have proven difficult, time consuming and costly, and likely would have produced less-than-perfect results, so IBM brought in a business partner, Butterfly Software. This software firm based in the United Kingdom had developed a unique software product capable of thoroughly assessing an organization s backup environment, determining cost projections, recommending a replacement solution and providing a total cost of ownership comparison for the new backup and restore solution. This software tool the Butterfly Analysis Engine provided a solid starting point for the utility company to begin its consolidation effort. Butterfly Analysis Engine The Butterfly Analysis Engine includes a unique library containing efficiency and effectiveness statistics for various storage, server and infrastructure configurations. It provides a complete view of an organization s existing data and infrastructure, presents the findings in an easily understood format that enables organizations to assess the cost and risk implications of staying with the current environment, and compares that to the proposed consolidated backup environment. By using empirical data from the client s own systems, this capability ensures that organizations can make informed and confident migration decisions. Butterfly can automatically scan the backup and restore environment in minutes (without the need for host agents), process Butterfly Metrics (using up to 4,000 raw data indicators), and provide a comprehensive, easy-to-read, single-pane report. This report can be completed in only a matter of days with no disruption to production teams and can be used to: Visualize the size and complexity of the current environment Analyze exposure to risk and test recovery time and recovery point objectives View risk and performance indicators across the complete backup infrastructure Directly compare current and potential backup environments, even across proprietary systems with a supporting business case Investigate strategic options and compare alternative configurations Assessment and solution proposal After receiving the Butterfly Analysis Engine Report, the utility company gained an insightful picture of its backup environment, as shown in Figure 1.

IBM Software 5 The full report shown in Figure 1 identified specific hardware and software architecture information (as detailed in Figure 2) for the current (source) environment and revealed several key concerns: Multiple backup applications (with licenses and maintenance) were in use, including one very old version of CA ARCserve, four versions of Symantec NetBackup, seven versions of Symantec Backup Exec and three old versions of IBM Tivoli Storage Manager. 72 backup and media servers were spread across 22 sites. Two petabytes of backup data were stored on more than 10,000 tape cartridges. Predictive growth up to 125 backup servers and more than 22,000 tape cartridges was estimated to take place over the next three years. The Butterfly Analysis Engine Report provided the company with a topographical view of the environment, depicting each of its data centers, with the type and number of servers and storage devices in each data center. The report also displayed the recommended replacement architecture for the company, based on Tivoli Storage Manager. SOURCE Environment Source Software Architecture Source software environment based on NetBackup 5.1, 5.1 MP5, 6.5.6, and 7.0, ARCserve v7, Backup Exec v7.2, v7.3, v8.0, v8.5, v8.6, v9.0 and v9.1, Tivoli Storage Manager v5.4.0, v5.4.6 and v5.50 Earliest software release date May 2004 Standalone backup servers manually reported [detail unavailable] Seventy Two backup management servers in twenty two data centre locations FULL and INCR backup methodology and policy enforced throughout the environment 72 active backup management server addressing a total of 1091 client entities 1091 configured backup clients Active data retention policy vary from 14 days to Over 7 years Software agents in use are Sybase, NDMP, MS-SQL-Server, Filesystem, Oracle, MS Exchange, SAP Source Hardware Architecture Backup management server technology based on Windows 2003, Solaris and AIX-RS/6000, Novell Backups are conducted over the TCPIP network and via MEDIA Servers Total number of physical tape libraries is 20 Library types in environment are IBM 3576, IBM 3573, IBM 3584, Overland NEO and IBM 4560SLX 156 Physical tape drives Total physical volumes onsite reported 2340 Offsite physical volumes 8122 Tape volumes are produced for offsite recovery Single copy of production data on tape media Disk STAGING in use on backup servers 543 Active backup polices Manual tape handling in remote sites Hardware compression in use Figure 2: Included in the Butterfly Analysis Engine Report is an analysis of the source software and hardware making up the backup and restore infrastructure.

6 Consolidate your backup systems to save money and reduce risks Looking at the topology comparison in Figure 3, you can see that the company s current environment, shown on the left, has 72 backup servers distributed in 22 different locations. The proposed environment, shown on the right, consists of six backup servers in three strategically located data centers. The proposed storage solution dramatically streamlines the infrastructure, reducing the hardware components from 156 physical tape drives and 20 tape libraries to 30 Linear Tape-Open (LTO) Ultrium 5 tape drives in three IBM tape libraries. The proposed environment also includes four IBM System Storage ProtecTIER Deduplication Gateway devices for data reduction. Before After Figure 3: The report s topology comparison can provide dramatic results, demonstrating how sprawling and complex backup and restore systems can be significantly streamlined.

IBM Software 7 Cost analysis revealing tremendous savings Butterfly has built years of best-practices experience into its Analysis Engine Report calculations, which were instrumental in creating an insightful report for the utility company. As shown in Figure 4, the savings the utility company can expect to see over the next 36 months after transforming its data-protection environment can be substantial, including the following potential hardware and cost reductions: 94 percent reduction in the number of tape cartridges (22,307 to 1,167) 90 percent reduction in the number of tape drives (323 to 30) 94 percent reduction in the number of tape libraries (52 to 3) 95 percent reduction in the number of master and media backup servers (126 to 6) 93 percent reduction in power usage (459 kva to 31 kva) Overall, the Butterfly Analysis Engine Report calculated a three-year infrastructure savings of 54 percent and an overall savings of nearly USD5 million. The report also included a detailed breakdown, shown in Figure 5, comparing the 36-month projections for the source (before) and the target (after) infrastructures including the type and number of hardware components, the power usage of the components and the total power usage.
