Abstract: In a database replication operation, a source end device obtains at least two groups of transaction logs from a log file of a source end database in parallel, where the at least two groups of transaction logs include a first group of transaction logs and a second group of transaction logs. The first group of transaction logs includes at least a first transaction log and a second transaction log that are adjacent to each other, and the second group of transaction logs includes at least a third transaction log and a fourth transaction log that are adjacent to each other, and a generation time point of the second transaction log is earlier than a generation time point of the third transaction log. The source end device then sends the at least two groups of transaction logs to a destination end device.

Abstract: Embodiments of this application relate to the field of storage technologies, and disclose a data backup method and a terminal, to back up user data in a terminal when the terminal cannot be used. A specific solution is as follows: A terminal includes a first data partition, and the first data partition supports to start an operating system when the terminal is powered on. The terminal starts the operating system by using a second data partition after detecting a power-on failure of the terminal or detecting a preset operation of a user. The second data partition is a blank data partition. After the operating system is successfully started, the terminal transmits user data in the first data partition to a first storage medium. The first storage medium is located outside the terminal and is connected to the terminal.
