HP DP 7.0 --How to create a scheduled backup job in CLI

Hi All,

   I got a question and hope u can help, I am new to HP DP, I know how to created a full backup job using CLI like this:

C:\Windows\System32>omnib -winfs my-machine:/c  -device mydevice1_Writer0
-mode full -tree \test             （full backup the "c:\test" to mydevice1）

My question is how to add a schedule to it? such as,On Monday/Friday I want do incremental backup and the Tuesday/Thursday I want it to do Full backup. 

Any help is appreciated,thanks in advance.
