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.
