May I suggest to use ontape and Unix scripts? For example, there are
very good scripts made by Art Kagel (available at IIUG repository in
one of utils*_ak packages of utilities), reliable and easy to adapt to
your needs. I have very good experience with them in production. I also
backup databases and logs to file system, then those files to library
using Legato. Fast, simple, low resorce consuming and reliable.
Ontape is much simpler to learn and use than onbar, although somewhat
limited. But those limitations often are not important in practice (for
example, for my deployments it's enough to have one fast data stream
for backup etc).
If you ever need a restore (and chances are you will eventually :(, you
will understand the value of simplicity of recovery process. And it's
hard to find any simpler RDBMS backup/restore tool than ontape, not
only in Informix world.
On the other hand, if your needs can't be satisfied with ontape, OnBar
is available with bundled ISM (Informix Storage Manager) that is, I
think, some version of Legato Networker. AFAIK, ISM is available to you
with no extra charge when you have IDS license.
