is this the right syntax for excluding a filesystem?

   exclude            /.../unix/../
   exclude            /.../core/../
   exclude            /.../.SpaceMan/.../*
   exclude.fs         /.../u01/.../*
   exclude.fs         /.../u02/.../*
   exclude.fs         /.../u03/.../
   exclude.fs         /.../u04/.../*

OR
should we use the:


   exclude.dir     /u01/*
   exclude.dir         /u02/*
   exclude.dir         /u03/*
  exclude.dir         /u04/*

The mounted filesystems are :

/dev/u01lv       15466496  10011152   36%      860     1% /u01
/dev/u02lv       15597568  13718904   13%     2498     2% /u02
/dev/u03lv       15597568   5892928   63%      478     1% /u03
/dev/u04lv       15466496   8779884   44%     6218     3% /u04
