Script help

[rockies]

I had script that works as below for automatic reboot which start at 3.00 o'clock and sysbackup start at 5.00 o'clock
for all server. I wana some modification as below.
I wana join this and make it at the same time . OR

First Reboot Second intergrity check( To check that machine is up and all deamon ( e.g batabase , webserver or automount) are up and working then starts Third sysbackup.
so is there any ways we can add some thing that works simultaneously


Below is the existing script of our all server :--
