I guess you are asking if you can use a TSM client without a TSM server to
get a backup? The answer to that is no. The TSM client must be configured
to point at some server that will accept you for open registration, or where
you are pre-registered.

The server is comprised of a DB and recover Log, and in most cases disk/tape
resources to handle actual backup data. The DB holds the node information,
directory entries of backup files, and pointers to actual data on its disk
and tape resources. The server has registered clients, that are bound to
'domains' that tell the server how to treat the indivdual files for that
node (how long to retain them, how many copies to keep, what goes to disk,
what goes to tape, what goes to optical, etc).
The client holds a configuration file that tells it where the server is, what
disks and/or files to back up, along with other information.
When the client starts a backup, it communicates with the TSM server database
and compares the state of a file, to see if it needs to be transmitted to
the server for storage, marked for deletion, etc.
This is a very simple view of how things work between the server and client,
but the client is pretty useless without a server to talk with. The client
has no concept of where files get backed up.
The client software is free and can be downloaded from IBM. The server runs
on various platforms (windows, Linux, AIX, HP/UX, Solaris), but of course
is not free. It's price depends on the number of client CPU's, and the type
of functionality you need in the server, such as disaster recover manager,
enterprise type library managment, etc.
There are try and buy servers available for download, that have limited
licenses, that allow you to get a feel for it. If you have a little bit of
disk space, you can set a server up on AIX in just a few minutes.
