Not if the client locally has compress=y in the optfile. That option
may override the setting in the schedule.
If you want to make sure a directory, or series of files don't compress
use the exclude.compress option.
If you want to turn off compression for the whole client add compress no
to the sys or opt file, or add a Client Option set compress=no with the
override set.
Also to make sure compressed files never grow when compression is active
add compressalways=no to the dsm.opt or sys file.
Clear as mud? Hehe.
If I were a betting man I'd say the dsm.sys has the compressalways=yes
option set as well as compression on.
