Morphology

back + up

The parts give partial clues: 'back' evokes movement toward the rear and 'up' often conveys accumulation or completion (compare 'pile up' or 'clog up'), so a learner might infer a sense of things building up. However, the specific sense 'become blocked/obstructed' for systems or pipes is a somewhat specialized extension and not fully predictable from the literal meanings, so prior exposure helps.

Etymology

Back up for files comes from the idea of keeping a copy at the back so you can pull it up if the first one is lost. So back up means 'to make a copy' to keep your data safe.
