Morphology

backup = back + up (transparent) = back + up

A 'backup' person is literally someone who 'backs up' another; the compound's meaning follows directly from 'back' + 'up'.

Etymology

Backup comes from the parts back and up, meaning someone kept at the 'back' ready to help. So a backup is a substitute who can take over when the main person cannot.
