Abstract

Embodiments of this application provide a hybrid-cloud data storage method and apparatus, a related device, and a cloud system. The data storage method includes: obtaining, by a gateway of a private cloud, to-be-stored data; determining partial data to be encrypted in the to-be-stored data, to obtain first target data; obtaining a first ciphertext obtained after the first target data is encrypted, the first target data being encrypted according to a first key provided by an encryption chip connected to the gateway; generating second target data including the first ciphertext according to the first ciphertext; generating a data slice corresponding to the second target data according to the second target data; and transmitting the data slice corresponding to the second target data to a public cloud for storage.
