Abstract: A method for backing up data in a data center, device and system are provided. The data in all the VMs of one data center can be backed up simultaneously, and the associations between the VMs are also backed up during the backup, so it is unnecessary to concern the recovery orders of the VMs when the data of the data center is recovered. Meanwhile, when the stored data is exported from the hypervisor node, it is unnecessary to notify the upper layer OS for a backup, thereby improving the data backup efficiency and reducing the system logical complexity.
