ADDITIONAL INFORMATION:

I have my backup set for Sundays at 6:00 and got a notification this morning (monday at 6) about a successful backup, and just now (still monday, 9:00pm) about a failed one.

Something seems indeed wonky about the scheduling.

I guess there’s some kind of automatic backup straight out of the Nextcloud account itself that isn’t tied to the Backup settings. The funny thing is that even the cycle of every 20 Minute doesn’t Match any of the possible cycles from the account setting (I personally Set the sync cycle to 15 minutes).
Maybe we need to disabled Backup in the Nextcloud account settings and hopefully the Backup will run as expected from generell Backup settings?
