At the moment automatic backups are taken 'every few days' (I can't find how many days exactly, but I know it's way too many).
I was having the following idea:
- Users pay 1$ per month to enable automatic backups
- Depending on their plan, they have a few slots available (you'll unlock additional slots by upgrading to a better plan)
- You can choose your own interval (twice a day, once a day, once a week)
- If you run out of slots, the oldest backup will be destroyed automatically to make space for a new backup
This way everyone can choose their own interval but everyone will get and pay the same.
