I disagree, a backup does not necessarily have to be a single file or a 
set of files. Wikipedia has this definition:
  "backup refers to making copies of data so that these additional   copies may be used to restore the original after a
dataloss event."
 

While for "replica", it states:
  "replica is a copy that is relatively indistinguishable from the   original"

Thus a backup can very well be thought of as replica, and vice versa.

That's certainly plain wrong, see multi-master replication where 
failover doesn't make any sense. Wikipedia again (although that's 
unfair, as I've contributed to that definition myself) [1]:
  "Replication is the process of sharing information so as to ensure   consistency between redundant resources"

..for example a master database and a backup.

A backup IS a replica. A backup IS a replica. A backup IS a replica. A 
backup IS a replica...
