At the recent Gartner IOM 2010 conference in Orlando, Florida, I had the good fortune of listening to a series of interesting topics and meeting some really smart people. As one might have guessed, the bulk of the sessions focused on virtualization and cloud topics. But the one topic that piqued my interested was unrelated to virtualization and cloud - it was deduplication and was hosted by Dave Russell.
The intent of the session was to bring forward a some customer examples that were deploying deduplication technologies in their backup and recovery solutions. Most of you that read this blog know that deduplication and data reduction have been a hot topic in the industry. And as you likely know, almost every major vendor out there offers some form of deduplication with its associated benefits.
This session provided us two customers who were willing to talk about their experiences with deduplication and the benefits they've received. One customer is using CommVault and the other is using IBM Tivoli Storage Manager v6 (TSM). While both customers showcased the quantified benefits from deduplication, the presentation from the TSM customer went beyond just the benefits of deduplication. The TSM customer revealed their quantified benefits and also identified some of the best practices they developed regarding deduplication.
This particular TSM customer is a large producer of natural gas in the U.S. The customers environment has TSM managing about 1.3 petabytes of data from over 1500+ nodes. Overall, their approach to managing backup storage is do it as efficiently as possible and to reduce the overall amount of backup data under management.
Prior to leveraging TSM deduplication, this customer began with "incremental forever" and compression. Once TSM v6 was released, they adopted deduplication at the server and client in concert with the other data reduction features provided by TSM.
As they began evaluating their use of deduplication, they had to deal with demands from their internal customers - DBA and Exchange admins like full backups etc. Furthermore, they had to consider how their rate of data change, evaluate retention policies, and ensure that their restore requirements weren't negatively impacted by the use of deduplication.
After significant testing and planning, the customer decided that they would initially deploy deduplication for their Oracle databases and Windows OS and system state backups. The results of using TSM deduplication were impressive ...
Oracle deduplication results - 75% reduction of Oracle backup data after deduplication. This was on 3.8TB of physical space on disk and about 15 TBs of data on tape.
And their results on Windows OS and System State were a whopping 94% ... taking them from 172GB of managed data down to 11.4 GB. In this scenario, the customer leveraged TSM 6.2 client- or source-side deduplication.
Overall, very impressive results. By leveraging the data reduction features within TSM, the customer was able to save by using less tapes library cells, tape drives, and disks.
In the end, the customer stated that TSM data reduction (with deduplication) helped them meet their objectives - efficiently reduce data under management. Furthermore, it allows them to reduce their overall HW costs and meet or improve restore requirements. The last comment the customer made before closing the session was that with all the various TSM data reduction capabilities in production, their job had ultimately gotten simpler now that their environment was running more efficiently ...
This is a fantastic story that I really enjoy sharing. If you are a TSM customer and have benefited from its data reduction technologies, then please give me a shout as I would like to hear your story as well.

Chapter 5: Unified Recovery Management – How IBM can Help
In my earlier postings on the topic of Unified Recovery Management (sorry for being away for so long), I laid out in excruciating
detail the complexity that is facing today’s backup administrators: many different applications, on different hardware/OS platforms,
in different locations, with different recovery point and recovery time objectives (RPO & RTO) to meet the operational requirements
of the organization.
In the last entry, I covered some of the many technologies that are available and widely used to address different aspects of this
complex issue. At the heart of the problem is, can any one backup administrator really have true visibility and control of the
entire data protection and recovery process when there are so many solutions and interfaces used.
IBM Software has been working for several years to address this challenge by bringing our various data protection software products
under the control of a single management interface, which is also common with many other IBM Tivoli software products.
The goals of this development initiative are: to manage the entire data protection and recovery infrastructure from a single
administrative interface; to unify the management of data within an integrated portfolio: and to understand where all the recovery
points are, manage them efficiently, and provide the interfaces to recover whatever data is needed, where ever it resides.
This interface is called the Tivoli Integrated Portal (TIP), and from it you can launch, monitor and manage the various Tivoli
Storage data protection and recovery software products:
simplifying management tasks.
A unified Recovery Management approach, such as offered by IBM, can:

I wanted to share some information about an article that we just published with regards to backing up Exchange Server 2010.
Along with all the other new features of Exchange Server 2010, Microsoft introduced Database Availability Groups (DAGs). DAGs are part of the large focus that Microsoft put on High Availability and Site Resilience within Exchange Server 2010. DAGs allow you to have passive database copies (aka "replicas") that can serve as hot standbys for protection against machine failures, database failures, network failures, viruses, or other issues that may cause an access problem to a database.
DAGs are similar in function to Exchange Server 2007 Cluster Continuous Replication (CCR) replicas. However, they extend the capabilities even further. One of the key benefits that customers get when they use DAGs in their enterprise is the ability to completely offload backups from their production Exchange Servers. That means they can run all of their backups from a database copy instead of the production database so as not to impact their production Exchange servers. This enables the production Exchange Servers to spend their resources on doing what they know best, i.e. handling email and facilitating collaboration.
IBM Tivoli Storage Manager for Mail : Data Protection for Exchange and IBM Tivoli Storage FlashCopy Manager completely support backing up DAG passive database copies. Data Protection for Exchange and FlashCopy Manager also support using those backups to recover the production database as well as for recovering individual mailboxes and items. You can find more details in the IBM Tivoli Storage Manager for Mail: Data Protection for Microsoft Exchange Server Installation and User's Guide V6.1.2.
We just published an article (which includes a sample script) to help you automate backing up your Exchange Server 2010 DAG databases. We know that you will find this quite helpful in setting up your backup strategy:

Working with IBM, a hospital in Asia Pacific gained a data protection solution that meets users' data availability requirements,
scales on demand to support a growing warehouse of patient data and medical images, and simplifies data migration and
data recovery tasks.
The benefits of the solution include a 50% reduction in backup window; restores individual Microsoft Exchange objects in minutes;
restores systems in under 10 minutes.
Read the complete case study to see how this Asian Pacific hospital gained peace of mind with virtualixed data protection from IBM.
