Tiered Storage
Tiered Storage
•Various medias are “virtualized”
•Advanced disk storage pool support
•Parallel backup of multiple clients
•Mixed retention in same storage pool
•Restores optimized for location of data in hierarchy
•Automatic migration to new tape technology
•Automatic migration to tape outside of backup
window
•Data is brought into hierarchy via Backup, archive,
HSM, SSAM, API, Bare Machine recovery, CDP …
•Data can be Copied, Migrated, Moved, Audited,
Staged, Checked for errors, Encrypted, Expired,
Imported/exported

Tivoli Storage Manager Bare Machine Recovery
Bare Machine Recovery
Brings back system to state of last backup
•Recovers all the OS changes and customizations
Streamlines and automates the OS recovery
process
•Eliminates the need for highly skilled professionals
to manually reinstall hardware, network, patches…
•Speeds up the recovery time
Integrates bare machine backups directly to
Tivoli Storage Manager server

Benefits
Ensure business continuity
•Restore systems back to original
state rapidly, therefore, getting
business back up and running
faster
Reduce administrative costs
•Enable less technical people to
run the recovery, because all the
critical networking, patches, device
driver information will automatically
be brought back
Maximize current hardware
investment
•By integrating with TSM, there is
no additional hardware needed to
support the bare machine recovery

Tape Reclamation
TSM moves data on off site tapes to save restore time, shelf space and money
Reclamation
When a tapes dead space reaches policy’s
threshold
•Tape is mounted
•Valid data moved to another tape
•Original tape returned to the scratch pool
Can be scheduled to occur at specified times
User-defined reclamation threshold
