exclude rule help



I'm trying to create an audit rule to exclude all rsync actions when run
by a process with a certain subject type (jcdx_fsbackup_t).

Our policy allows the action to happen, however as a result we generate
a ton of audit data on file access and recreation at the target point.

Anyone have a good idea of how to discard all these events? Ideally the
caller would send in a self-generated event such as "ryncing rick/src2/
to /temp-home" or similar. This is for a dedicated file backup
procedure.

Obviously I do not want to discard all rsync events, just when launched
by our trusted program. Nor would I really want all that program's
events discarded since I want it to be able to submit proactive events
which summarize its behavior.

Below are some event samples. Other ideas are welcome also if my
approach is myopic/flawed.

Thx,
LCB.
