TDP for Informix is just a XBSA interface between Informix On-Bar and
Tivoli Storage Manager.
So if for you fragmented means tables are in more than one dbspace then you
can backup only some dbspaces. It is up to you (or your DBA).
But be aware that you will not be able to perform cold restore of the
server in this manner. Only mixed restore - cold restore of rootdbs
followed by warm restore of dbspaces backed up.
There are not too many thing to tune/control using TDP for Informix. The
backup process is under control of On-Bar.
If you are having problems notify us.

Subject:        Using TDP with Informix on a 1TB fragmented database

Our company has just converted to TSM from Veritas NetBackup. We have our
first TDP customers with Informix and Oracle to set up. These servers have
multiple database instances on the same server. One of the Informix
databases is 1TB and is fragmented. (The Oracle server, also has a 1TB
database.) They want to backup only specific fragments at a time, probably
around 300GB. We have a SAN and will attach them to the SAN in the near
future, but at first we are going to be using a small development database
on this server to test TDP.

Can any of you please give me your advice on what worked best for you when
setting up TDP? Thank you!!
