Low performance of HA Backup

I was using onedrive backup add-on until onedrive support has been provided in HA core backup integration. I am observing that performance of the integration is quite lower than the performance of the add-on. In my case, the add-on was taking around 1 minute to generate backup and 3 mins to upload → total 4 min for a 450 MB size backup.
On the HA Core integration it is taking around 7 minutes for generation and upload of same size of backup. It is surprising to observe such big difference, taking into account that backup engine is really same in both cases.

Hello Pedro,

Do you have a question?

Is there a reason for such difference? Is there opportunity to improve performance of integration, taking the addon case as reference of feasibility?

You could add a feature request with your findings.

Just change the catagory of this to Feature Request and add more of your findings, or screenshots, or whatever you need to make your point in the top post.
You could also just keep using the add-on you found if you like.
