Morphology
have + (someone's) + back
The phrase combines 'have' (possess/hold) with 'back' used in the sense of support, so the overall meaning 'to support or protect someone' is directly derivable from the constituents. This possessive + noun composition is a common, cross-linguistic way to express backing, so a B1 learner who knows the words would very likely infer the intended meaning.
Etymology
Have (someone's) back makes you picture someone standing behind your back to protect you and help if there is trouble, so it means 'to support or protect someone'.
