Quick Start
Tivoli Storage Manager provides automated, policy-based, distributed data
and storage management for file servers and workstations in an enterprise
network environment. The base functions provided by TSM include:
- Backup and Restore:
- The backup process creates a copy of file or application data that can be
recovered if the original data is lost or destroyed. Unlike other
backup applications, TSM implements a progressive backup
methodology to move data quickly and reliably. Using progressive
backup, the number of file versions maintained by TSM and the length of time
they are retained can be specified by the storage administrator. Refer
to Common Backup Methodologies for more information.
Backups can be scheduled, performed manually from the TSM client interface,
or performed remotely using a Web-based interface.
The restore process transfers a backup data copy from TSM server-managed
storage onto a designated machine.
- Archive and Retrieval:
- The archive process creates a copy of a file or a set of files and stores
it as a unique object for a specified period of time. This function is
useful for maintaining copies of vital records for historical purposes.
Like the backup process, the archive process can be scheduled, performed
manually from the TSM client interface, or performed remotely using a
Web-based interface.
The retrieval process transfers the archival data copy onto a designated
machine.
- Instant Archive and Rapid Recovery:
- Tivoli Storage Manager allows for the creation of a complete set of client
files, called a backup set, on the TSM server system using the most
recent backup versions stored by the server. In a process called
Instant Archive, a backup set is used to retain a snapshot of a
client file system for a designated period of time. The Rapid
Recovery process allow you to copy backup sets onto portable media for
LAN-free recovery of a client system.
Tivoli Storage Manager also offers a number of separately licensed optional
features. These include:
- Disaster Recovery Manager:
- Planning for disaster recovery involves implementing and automating the
processes needed to recover from a major loss of enterprise infrastructure and
data. These processes can include moving data to an offsite storage
location, rebuilding the infrastructure, and reloading data as quickly as
possible. Disaster Recovery Manager (DRM) facilitates the creation and
testing of a disaster recovery plan by providing scripts and procedures for
automating the restoration process. DRM also facilitates the tracking
of media stored offsite.
- Tivoli Space Manager:
- This feature provides for the automatic and transparent movement of
operational data from a client system to server-managed storage. This
process, called Hierarchical Space Management (HSM), is implemented
as a client installation and controlled by policy defined to the TSM
server. HSM frees up space on a client machine by using distributed
storage media as a virtual hard drive for that machine. Files are
automatically moved and stored according to size, age, and usage. When
a user accesses this data, it is dynamically and transparently restored to the
client machine.
