5.4 Recovery management

As part of the IBM TotalStorage Open Software Family, the IBM Tivoli Storage

Manager protects organization's data from hardware failures and other errors by

storing backup and archive copies of data on offline storage. Scaling to protect

hundreds of computers running a dozen OS ranging from laptops to mainframes

and connected together via the internet, WANs or LANs, Storage Manager's

centralized Web-based management, smart-data-move and store techniques,

and comprehensive policy-based automation all work together to minimize data

protection administration costs and the impact to both computers and networks.

Optional modules allow business-critical applications that must run 24x365 to

utilize Storage Manager's centralized data protection with no interruption to their

service.

Data backup and restore

Backups are copies of your active online data stored on offline storage. Should

an online storage device fail, a data error occur, or someone accidentally deletes

a file, the offline copy of that data can be copied (restored) to online storage. IBM

Tivoli Storage Manager uses multiple techniques to make data backups and

restores as fast, flexible, and low-impact as possible.

Managed data archive and retrieve

Data archives are copies of active or inactive data from online storage copied to

offline storage. Archives are used to keep point-in-time copies of important data

for regulatory or bookkeeping requirements and to move inactive data from

expensive online storage to less-expensive offline storage. Managed data

archives implemented by Storage Manager are managed for a defined lifetime

through the policy-automation engine, just like backed-up data. The Storage
