archiver

1 :  a person who creates or maintains an archive :  archivist Few architects’ names resonate across the centuries with the force of the 16th-century Italian Andrea Palladio, the great Renaissance archiver of the classical orders and the inventor of the modern villa. — Andrew Ferren, New York Times, 27 Dec. 2009

2 :  something (such as a computer program) that is used to create archives An archiver that doesn’t support searching—on the bodies of messages, as well as on authors and subjects—is close to useless. — Karl Fogel, Producing Open Source Software, 2006
