Dear @fataugie,
Thank you for sharing your findings! We have added the method you described to our documentation

Hello @CJ,

Please accept my deepest apologies for the late response!!! I did not see the notification...

At first glance, your settings seem good to me as you have daily delta backups (now called incremental) combined with full backups every week. Now, I quite don't understand how a full backup could happen during the week (as it is scheduled to happen during weekends if I understand well). Do you sometimes change de settings or could you say if it happens on a regular basis?

I have asked the XO team to help me understand how this could happen, if there is something to do with the retention maybe. My response is not precise for now as I wanted at least to tell you that I finally saw your message. Sorry again about that.

Also, I agree we should update our documentation and I am definitely open to suggestions. I will gather some information and be back to you as soon as I can.

Noted @olivierlambert. Posting back here when it's done.

Dear @CJ,

We have added an article in our documentation that explains why full exports sometimes happen unexpectedly. You can find this article on this page.

I hope it clarifies, do not hesitate to tell us your opinion!
