conditionally quit snapcreator backup job

Hi,

I am using sybase plugin fro snapcreator.  I have this requirement.

1. Check whether full sybase file level backup is running prior to database quiece.  I plan to put this check script in PRE_APP_QUIESCE_ CMD01.

2.  If this check script detects that database full backup is running, it should quit this snapcreator job.  How can I do this?

3.  If this check script detects that no database backup is running, it should continue executing this snapcreator job, i.e., quiesce, snapshot, unquiesce.  This part is straight forward.

You help is appreciated for point #2.

Thanks.
