Disabling the "backup before updating" feature?

[Trezona]

Hello @beeyev.
Would it be possible to disable the "backup before updating" feature?
I really don’t see the need for it if one is using the script often, like every second or third day.
If there are any problems with the new OS version, I can roll back to the previous version a few days back.
Thanks very much.
Clive.
