To change backup time you can just change the cron job for /scripts/upcp, selecting the time you prefer.

OR

You can force a new daily backup by setting up a cron job for /scripts/cpbackup (in this case backups will run two times everyday)

OR

You can edit /scripts/upcp, remove or comment the calls for /scripts/cpbackup, and setup a different cron job for the [COLOR=blue !important][COLOR=blue !important]backup [COLOR=blue !important]script[/COLOR][/COLOR][/COLOR]. Note that cpanel updates may overwrite the upcp file, so you'll loose this changes.
