Feature description

Cleanup automatic backups, so only the latest x (7?) backups are kept.

Why do you want this feature?

If I enable automatic backups, after a while my backup location contains too many files and takes up too much space.

Additional information

only the latest x (7?) backups are kept.

I guess that should/could be optional (how many to keep)

And maybe it should be in org, so all apps use it

I'm not sure if this is related, but Calendar seems to save copies of sync'd calendars.

I store my calendar in Nextcloud via DAVx5, which means that it's not restored by SeedVault, but after restoring to the new phone Calendar seemed to still have my Nextcloud calendar available to it, complete with events. In my view, Calendar should not save the contents of sync'd calendars in its backup. (I did not test what happens in Calendar after setting up the Nextcloud connection with DAVx5, in case Calendar created duplicates; I just cleared Calendar's storage after restoring to the new phone.)
