Borg seems like the closest backup program like obnam. The main difference is it uses per-client AES keys, rather than gpg keys. So a backup can't be easily made accessible by other gpg keys.

I suppose that encrypting its AES key to the gpg keys you want to be able to access the backups, and storing the encrypted AES key alongside the backup will get the same functionality.
