Even if there are questions in [tag:restore] that are not related to backups, the tag excerpt is unambiguous:

> Returning data from a backup to its original location or to its successor.

While the name of the tag is ambiguous, its intended use is not; the tag was created on 2012/6/15 and this description was applied the same day. I suggest merging the tags and changing [tag:restore] to an alias.

(Ironically, [tag:backup-restoration] has no tag wiki description at all. The name says it all though.)
