ownCloud has version control ( https://doc.owncloud.org/server/8.1/user_manual/files/version_control.html), although you need to keep an eye on your server drive size. It will start to purge older versions if your disks exceed 50%. But by your definition this would still be considered a backup.
Also since I never delete from my S3 bucket where I have a nightly sync from ownCloud to, the risk of losing everything is low. I also have up to 24 hours to recover files that might have been written over. Given that I already have enough safeguards for my personal needs, should the need arise I could easily modify the sync process to do monthly full backups (tar/gz), then incremental tar/gz for files that are new or modified. As I mentioned, my solution may not be for everyone since I already have cloud solutions in place for my business, which makes it cheaper. But it's easily scalable to the amount of redundancy I want.
