Chapter 5. Backup and Restore 71
Strategies and operations description
The data at primary and off-site location are fully synchronized utilizing a high-bandwidth
connection. The two systems are advanced coupled, allow an automated switchover from one
site to the other when required. A Tivoli Storage Manager setup is installed at each location
and run independently, creating dual production systems. Each Tivoli Storage Manager
server is protected using BC Tier 2 or BC Tier 3 technology. See Figure 5-14.

5.2.3 Integrated solution capabilities of IBM Tivoli Storage Manager
Additional optional IBM Tivoli Storage Manager products are available that provide integrated
solution capabilities. These include:
򐂰 IBM Tivoli Storage Manager for Copy Services - Data Protection for Exchange
This provides integration of Tivoli Storage Manager with VSS providers on supported
storage systems to make fast, snapshot-based backups of Microsoft Exchange
databases. The snapshot can then be copied to a Tivoli Storage Manager server for longer
term, policy-managed storage. Optionally, the Tivoli Storage Manager backup of the
snapshot can be performed by a separate server, freeing up CPU resources on the
production Exchange server, known as offloaded backup. On a SAN Volume Controller,
instant restore is possible, where a snapshot can be rapidly restored back to the original
source disks using the hardware FlashCopy restore.
