A backup and an archive may include all or part of the original data. My own distinction between the two is this: In a backup, the data on the original remains intact. In an archive, some or all of the archived data may be erased. Obviously there is a lot of overlap. Backups are for security and archives are for permanent storage, but to some extent either can be used for the other purpose.
