Calendar problems/iCloud

Hi
Today I found out I had duplicate calendars on my iPhone (because I synced with iCloud and Mac).*
So I deleted the Mac calendars from my iPhone 5, but deleted the iCloud calendars (accidentally) too. I logged into my Mac and saw that the iCloud and Mac calendars were already gone.
No problem, I'll just restore them from a backup, this gives my calendars back on my iPhone but not on my Mac, which means when the two sync with each other, the calendars disappear again.
How can I solve this?

Thanks

I've had similar problems with duplication - you'd think Apple's software would be able to track down duplicate entries and display them only once (as in, you know, it just works).... I wish I could be helpful about the question you posed, but I do not have any suggestions.

I found how to get them back on my iPhone:
I restored the back-up, then went quickly to my iCloud settings on my iPhone and turned the option for Calendars off (but kept all the event entries on my iPhone).
Followed by an iCloud back-up (assuming the calendars would stay on iCloud)
Turned the calendar option for Calendars back on and synced my iPhone with my Mac.

Result: the calendars were added to my Mac, but WITHOUT EVENT ENTRIES.
Going to do an iCloud back-up again to get any better results.

How is it possible no one has had the same problem?
Please, any direction that leads to the right way to do it is welcome

Thanks in advance
