Delete TSM Backup driver
TSM backup driver is not supported by vendor for a while and deprecated in Victoria release, so it's safe to delete it now. Change-Id: I0ab07708843fcbb64bf932667e9b79aab259f698

"""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.

IBM Tivoli Storage Manager backup driver
|
||||
========================================
|
||||
|
||||
The IBM Tivoli Storage Manager (TSM) backup driver enables performing
|
||||
volume backups to a TSM server.
|
||||
|
||||
The TSM client should be installed and configured on the machine running
|
||||
the cinder-backup service. See the IBM Tivoli Storage Manager
|
||||
Backup-Archive Client Installation and User's Guide for details on
|
||||
installing the TSM client.
|
||||
|
||||
To enable the IBM TSM backup driver, include the following option in
|
||||
``cinder.conf``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
backup_driver = cinder.backup.drivers.tsm.TSMBackupDriver
|
||||
|
||||
The following configuration options are available for the TSM backup
|
||||
driver.
|
||||
|
||||
.. config-table::
|
||||
:config-target: IBM Tivoli Storage Manager backup driver
|
||||
|
||||
cinder.backup.drivers.tsm
|
||||
|
||||
This example shows the default options for the TSM backup driver.
