What feature do you want to see added?

I would like an option to be added where instead of deleting older backups, make the backups incremental to save space. There could also be an option where every month a full backup is made and previous backups get removed and then the rest of the backups are incremental backups from the last full backup. https://en.wikipedia.org/wiki/Incremental_backup

Are there any alternatives?
