There are several ways, I choose to add it to my maintenance script so I can 
control other processing.
You will need to define a device class (see command (define devclass)

The either create a script, or admin schedule to execute the "backup db" 
command.

All options for these commands are explained with the help system incorporated 
into the TSM CLI, or reference the Admin Guide for the version you are using.

Subject: [ADSM-L] TSM database backup

Hi,

How do you take a backup of the TSM database ?

Before it was DB2, we wrote the backup to disk.  And this backup was written 
with other relevant data (mksysb on AIX) to a remote drive or a simple tape 
streamer.
We also used usb sticks but they fail very often.    And they are not big
enough.
We also use RDX drives and they are much more reliable.
