Abstract: A virtual machine recovery method, where after receiving a virtual machine recovery command for recovering a to-be-recovered virtual machine, a virtual machine management device obtains configuration information of the to-be-recovered virtual machine from a cloud server. Then the virtual machine management device creates, according to the configuration information, a recovered virtual machine and a local storage. After downloading basic system data from the cloud server, the recovered virtual machine is started according to the basic system data. When receiving an input/output (IO) request for accessing a first data of the to-be-recovered virtual machine, the virtual machine management device downloads the first data from the cloud server to the local storage.

Abstract: A method, an apparatus, and a system for migrating virtual machine backup information, which implement backup information migration after a virtual machine is migrated. The method includes: receiving, by a first backup server, a migration trigger message, where the migration trigger message carries pre-migration virtual-machine identification information and indication information of a second backup server; determining, by the first backup server, backup information of the virtual machine according to the pre-migration virtual-machine identification information; and sending, by the first backup server, the backup information to the second backup server. Therefore, the migrated virtual machine inherits backup information existing before the migration, such that the migrated virtual machine continues to be protected by backup data existing before the migration, and data of the virtual machine is backed up according to a backup policy existing before the migration.
