When determining that the second-tier node (NFVM, VIM) changes, the first-tier backup unit 701 may obtain data and configuration information of the changed node as updated backup information corresponding to the first-tier Node (NFVO), and upload the updated backup information of the first-tier node to the storage module for storage, so as to update the backup information of the first-tier node. In an embodiment, the first-tier backup unit 701 is further capable of acquiring, when the first-tier node is initially created, data and configuration information of the second-tier node that is initially accessed and uploading the data and configuration information to the storage module as initial backup information of the first-tier node, so as to update the backup information of the first-tier node on the basis of the initial backup information of the first-tier node.
The second-tier backup unit 702 can trigger the second-tier node to upload the changed data and configuration information as updated backup information corresponding to the second-tier node to the storage module for storage when determining that the second-tier node changes, so as to update the backup information of the second-tier node. In one embodiment, the second-tier backup unit 702 is further capable of acquiring data and configuration information of a node initially accessed and uploading a storage module as initial backup information of the second-tier node when the second-tier node is initially created, so as to update the backup information of the second-tier node on the basis of the initial backup information of the second-tier node.
The third-tier backup unit 703 can acquire, when it is determined that a third-tier node has changed, data and configuration information of the changed node as update backup information corresponding to the third-tier node, and upload the update backup information of the third-tier node to the storage module for storage, so as to update the backup information of the third-tier node. In an embodiment, the third-tier backup unit 703 can further acquire data and configuration information of a node initially accessed when the third-tier node is initially created, and upload the data and configuration information to the storage module as initial backup information of the third-tier node, so as to update the backup information of the third-tier node on the basis of the initial backup information of the third-tier node.
In one embodiment, the first tier backup unit is located at a first tier node; the second layer of backup units are positioned at the first layer of nodes; the third layer of backup units are positioned at the second layer of nodes, thereby realizing the layered backup control.
In the resource backup system of the virtualization platform, the first layer node, the second layer node and the third layer node can be backed up by using the layered backup units, so that a part of backup authority of the NFVO is transferred, the processing burden of the NFVO is reduced, and the resource backup efficiency is improved.
In some embodiments, the first-layer backup unit 701 is further capable of acquiring the first-layer backup information from the storage module and restoring the first-layer node when the information of the first-layer node is lost. The second-tier backup unit 703 can also trigger the second-tier node that needs to be restored to acquire the second-tier backup information from the storage module and restore the second-tier backup information when there is an associated second-tier node that needs to be restored. The third-layer backup unit can also acquire third-layer backup information from the storage module and provide the third-layer backup information to the third-layer node needing to be restored so as to restore the third-layer node when the associated third-layer node needs to be restored.
In the virtualization platform resource backup system, when the second and third nodes need to restore data, the backup and restoration of the lower layer can be controlled through the node of the upper layer, so that the restoration efficiency is improved, and the capability of the system for dealing with emergency is improved.
