Abstract: A log data query method includes determining a target node matching a query time range from a log query time tree, a node in the log query time tree being configured to record a time range for a log query; determining a target subtree from subtrees under the target node and configured to search for a boundary time value corresponding to the query time range; performing leaf node traversal from an edge leaf node of the target subtree, and stopping the leaf node traversal after a target leaf node is traversed, a time value, within a target time range recorded in the target leaf node, having corresponding log data in a disk; determining a time value recorded in the target leaf node having corresponding log data and in a critical state, for obtaining the boundary time value; and obtaining log data matching the query time range from the disk.

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.
