This application provides a data storage method and apparatus, and a system. The method may include: A first device in a vehicle obtains data related to the vehicle. The first device packs raw data, compressed data, or a digest of the raw data into a block, where the block is a block in a blockchain. The first device publishes the block to one or more second devices. The one or more second devices store the block, and update a locally stored blockchain. In this way, data backup can be implemented without a connection to an external network. In addition, distributed storage of data (or event log records in a vehicle) based on a blockchain can further improve security. In addition, this application may be further used in the vehicle field, for example, an intelligent networked vehicle or a smart vehicle. This application may be further used in the in-vehicle networking field, for example, an in-vehicle Ethernet or a local area network in vehicle.
