Please reconsider. You would go in circles and no true backup. The push could write/change/delete any data obviously. This appeared as if some of the core arguments of your own, didn’t it?
Have a look on some more reasonable articles from the more reliable service providers. The below listed article is worth a reading and just an example of many.
Backups ensure that your critical data will survive any of the likely hazards.
Furthermore, there should be some sustainable storage concept if you truly want to have long time archiving of backups (> 10 years). There is much more to consider if you want to do this seriously.
Please continue in looking around and you may accomplish more from some research of your own in the long run. Good luck.
