Enterprise Strategy Group Report 2012 - IBM Tivoli Storage Manager 6.3

Deduplication, Remote Site Recovery, and Scalability

By Tony Palmer, Senior Lab Analyst

ESG Lab Validation Highlights:
- TSM 6.3 progressive incremental backup, combined with client- and source-side data deduplication technology provided an impressive 95% data reduction factor (more than 19:1) over just 11 days of backups.
- DB2 continues to provide an enterprise-class, scalable back-end for TSM. ESG Lab confirmed that TSM 6.3 can scale to more than four billion objects under management while providing higher performance and more functionality.
- TSM 6.3 offers hot TSM server disaster recovery, and demonstrated the ability to replicate deduplicated data sets from a live TSM server to a hot standby server. TSM 6.3 provided seamless and transparent restores for clients after failover.
- TSM 6.3 showed many improvements to ease of use and management. The Tivoli Integrated Portal (TIP) provided a common repository for all TSM interfaces, with a single pane of glass for management of an enterprise TSM environment. ESG Lab also tested automated client deployment, with no scripting or manual commands needed.
Issues to Consider
- Under Tivoli Storage Manager each source TSM server can replicate to one other TSM server. While a replication scenario is supported where multiple TSM source servers all replicate to the same target (many to one), a one-to-many configuration, with a source server replicating to multiple targets, is not supported in TSM 6.3.

The Big Truth:
ESG Lab performed hands-on testing of key TSM 6.3 features to demonstrate and audit its capabilities. ESG Lab tested client-side data deduplication to understand the value of this capacity optimization technique in combination with deduplicated storage pools and progressive incremental backups over time. ESG Lab found that the two technologies (deduplication and progressive incremental backups) working in concert were able to achieve 90% data reduction after just six incremental backups and 95% reduction after ten backups. Replication is also now fully integrated with deduplication, optimizing bandwidth for disaster recovery.
