Virtual machine snapshot backup based on multilayer de-duplication
The present disclosure provides an example method and system for virtual machine backup based on multilayer de-duplication. A virtual machine snapshot is divided into multiple child data blocks. Each child data block is divided into multiple data segments. Multilayer de-duplication is applied to the virtual machine snapshot to exclude data causing duplicate backup in the virtual machine snapshot. The remaining virtual machine snapshot data after the processing of the multilayer de-duplication is stored.
