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.

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
