I've searched carefully, but maybe I've failed to come up with good
search strings, so in case anybody knows of some non-intuitive options,
or maybe even a small third-party interface through the API...
 
I've got data sets that I need to retain for 53 weeks as complete
copies.  They're copies of informix databases - about 1GB per copy.
gzip significantly beats TSM compression, and I could cut the number of
objects to keep in the database by 389%, but I can't count on having
room for a tempfile
I'd like do something like this:

tar -cf - carma.dbs |gzip -9|dsmc ar $PLANT.`date +%Y%m%d$H`.db.tar.gz
-filehandle=0 -archmc=plant_53week

Instead of this:

tar -cf - carma.dbs |gzip -9>$PLANT.`date +%Y%m%d$H`.db.tar.gz;dsmc ar
$PLANT.`date +%Y%m%d$H`.db.tar.gz -archmc=plant_53week -filesonly
-deletefiles
 
I figure I'm just smoking crack, but might as well ask.
