Embodiments of the present invention provide a method, a computer, and an apparatus for migrating memory data. After receiving a first trigger instruction, a processor can exit an operating system and execute a memory data migration instruction of a basic input/output system, where the memory data migration instruction of the basic input/output system enables the processor to determine a source memory card of to-be-migrated memory data, determine a backup memory card for the source memory card, and instruct a memory controller of the source memory card to migrate the memory data, so as to enable the memory controller of the source memory card to read the memory data of the source memory card and write the read memory data of the source memory card into the backup memory card according to an instruction of the processor, so that the memory data of the source memory card can be migrated in a case in which a computer is not powered off, thereby implementing online maintenance of a faulty memory card, and solving the problem in the prior art that a faulty memory card can be replaced or maintained only when an entire computer is powered off. |
