Tvheadend

Hello, i found this script here;
https://tvheadend.org/projects/tvheadend/wiki/Wakeup

It works good. I'm not a script professional, so I need help:

My tvheadend server must wake
1) before recording started
2) every day at 5:00 am for server backups

How can I add 2) on the script?

Thx for help
