Morphology
at + rest
The sense 'not moving or inactive' follows directly from combining 'at' (indicating a state or location) with 'rest' (a period of stopping activity), forming the common pattern 'at X' = 'in a state of X'. The technical usage 'data at rest' is just an extension of this transparent meaning (data that is not being transmitted or processed), so a B1 learner who knows the constituents would likely infer the MWE's meaning.
Etymology
At rest in computing comes from the image of files sitting on a shelf and not being moved. So 'data at rest' means the information is stored on a device and not being sent or used.
