I assume you're doing RMAN backups to disk and want to save these data with TSM.

One way to do this is using  'selective'.
The 'selective' command backs up files/directories that you specify.
During a selective backup, copies of the files are sent to the server even if they did not change
since the last backup.

An example:

dsmc selective -subdir=yes "/my/rman/diskbackups/*"

Note that files saved this way are subject to the same rotating scheme as incremental backups
(versions, active retention, deleted retention).

To run a selective backup via TSM scheduler, define a schedule (via dsmadmc or GUI) in the following way:

define schedule [domain] [schedname] action=selective objects="/my/rman/diskbackups/*" options="-subdir=yes" [your options for time, day, frequency ...]

and issue

define association [domain] [schedname] [nodename]

Remember to have the client scheduler process (dsmc sched) configured and running on your node.

Perhaps you should exclude the directories in question from regular incremental backups:

If it's a filesystem of its own, simply add to /usr/tivoli/tsm/client/ba/bin/dsm.sys

DOMAIN -/my/rman/diskbackups
in addition to your normal DOMAIN options (note the dash ( - ) in front of the directory string)

If it's a directory only, add to /usr/tivoli/tsm/client/ba/bin/dsm.sys

exclude.dir /my/rman/diskbackups

Don't forget to recycle the client scheduler after making changes to dsm.sys.

A second way is using archive.

I'll come back later and explain (no more time now ...)

OK, I'm back.
Now for 'archive'.
With 'archive', you create a copy of files/directories in their current state in long-term TSM storage.
There is no rotating scheme, only a single parameter, the RETAIN time, which is by default 365 days.
This parameter is set in the archive copy group of the default management class of your node's domain.
You can, however, create an additional management class and an associated archive copygroup for your domain, change the RETAIN setting in this copygroup, and then use this management class during archive (see below).
There is no automatic versioning, you can create as many archives of the the same data, changed or not, as you like.
You can delete specific archives (by the delete archive command), given your node has the 'archdel=yes' setting.
An archive is accompanied by a descriptive string, which you define and which can be used for reporting and retrieval.
Data is retrieved from archives using  'retrieve' (NOT restore!)
An example
dsmc archive -subdir=yes -desc="2009-02-13 Regular archive of RMAN disk backups" "/my/rman/diskbackups/*"
If you configured a non-default domain/set/mgmtclass/copygroup scheme containing a customized RETAIN setting, use
dsmc archive -subdir=yes -archmc=rmanmc  -desc="2009-02-13 Regular archive of RMAN disk backups" "/my/rman/diskbackups/*"
(I named your new management class 'rmanmc', obviously).
Creation of a schedule is done exactliy as with selective, with an action=archive and options as appropriate, e.g.
options="-archmc=rmanmc -subdir=yes"
selection of archives to retrieve is possible in several ways - by fromdate/todate, by pick, by description or without selection (for the newest)
retrieve -replace=yes "/my/rman/diskbackups/my_desired_backupset"
Finally, apart from selective or archive, you can alway use
incremental -subdir=yes "/my/rman/diskbackups/*"
Note that only changed files will be saved and that your defined retention policies apply.
