Some people would call that an archival system. While it is true that most backup systems allow you to recover deleted/old version of files, it's not clear that is a required part of a backup system in the strictest sense. Still it comes in handy and has been a typical feature of most backups systems so being aware of when it isn't available is well worth knowing.
