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:
backup_driver = cinder.backup.drivers.tsm
The following configuration options are available for the TSM backup driver.
| Configuration option = Default value | Description | 
|---|---|
| [DEFAULT] | |
backup_tsm_compression = True | 
        (BoolOpt) Enable or Disable compression for backups | 
backup_tsm_password = password | 
        (StrOpt) TSM password for the running username | 
backup_tsm_volume_prefix = backup | 
        (StrOpt) Volume prefix for the backup id when backing up to TSM | 
This example shows the default options for the TSM backup driver.
backup_tsm_volume_prefix = backup backup_tsm_password = password backup_tsm_compression = True
