Tivoli Storage Manager





IBM Tivoli Storage Manager (TSM or ITSM) is a centralized, policy-based, enterprise class, data backup and recovery package. The software enables the user to insert objects not only via backup, but also through space management and archive tools. It also allows retrieval of the same data via similar restore, recall, and retrieve methods.
This product is part of the IBM TotalStorage suite of products and is unrelated to Tivoli Framework.
The product was known as ADSTAR Distributed Storage Manager (ADSM) before its 1999 re-branding, and was originally known as Workstation Data Save Facility (WDSF).

TSM maintains a relational database (limit 534GB through TSM v5.5, 4TB with TSM v6.3.3+) and recovery log (aka transaction log, limit 13 GB through TSM v5.5, 128GB with TSM v6.1+) for logging, configuration, statistical information, and object metadata. v5.5 DB pages are always 4KB, and partitions every 4MB. Single row inserts only. On average, 20GB of space is consumed for every 25 million objects. Shallow directory structures use less TSM DB space than deeper paths. This database may generally be queried via an emulated SQL-98 compliant interface, or through undocumented SHOW, CREATE or DELETE commands.
Actual user data is managed via a cascading hierarchy of storage media (Primary Storage Pools) presented as raw devices (UNIX), filesystem containers (Windows and Linux), streaming tape or optical media. Additionally, emulated tape from a Virtual Tape Library or EMC Centera WORM archival device are supported. Duplicate copies (Backupsets or Copy Storage Pools) of any subset of data may be created on sequential media for redundancy or off-site management.


 FastBack Bare Machine Recovery (BMR) :
     ·         You mount volume directly from Tivoli Storage Manager server storage
·         You restore individual files from volume level backup
·         Tivoli Storage Manager 6.2 API is now part of FastBack Mount
·         You do not require FastBack server for File Restore
·         File Restore now has support for Windows and Linux®
·         The backup that you restore from can be a deduplicated Tivoli Storage Manager storage   pool

Design Requirements for Seismic Safety of  Nuclear Power Plant:

Your data is sent from your computer, across the university network to the HFS servers and is then ultimately stored on magnetic tape in an automated (robotic) tape library. 


 



Our servers and tape library are situated in a climate-controlled, secure location

Tivoli Storage Manager is a complete storage management solution that is
designed to use many components to handle individual circumstances and
special needs. As we move forward, we will see that Tivoli Storage Manager is
uniquely designed to provide a compete and full solution. Clearly, no single
product will be able to resolve every problem or handle every situation. Tivoli
Storage Manager is constantly adding and filling in gaps and weakness with new
features and add on products to fulfill storage management solution needs.
Next we shall consider planning and the importance of ensuring that your goals
and requirements are realistic and obtainable with the hardware, software, and
resources at your disposal.
