The cinder.backup.drivers.tsm Module

Backup driver for IBM Tivoli Storage Manager (TSM).

Implementation of a backup service that uses IBM Tivoli Storage Manager (TSM) as the backend. The driver uses TSM command line dsmc utility to run the backup and restore operations. This version supports backup of block devices, e.g, FC, iSCSI, local as well as regular files.

A prerequisite for using the IBM TSM backup service is configuring the Cinder host for using TSM.
