Abstract

Virtualization snapshots are utilized for efficiently synchronizing virtual machines present on a client system and a server system. A snapshot of a virtual machine (VM) is taken by the client system before making modifications to the VM. The modifications to the VM are stored by the virtualization snapshot separate from the VM itself. The modified portions of the VM are communicated by the client system to the server system. The server system applies the modifications to a locally stored VM that corresponds to the original VM on the client system. The modified VM on the server system matches the modified VM on the client. As a result synchronization between the VMs on client system and the server system is obtained without transferring the entire VM multiple times. The server system performs format conversions between a format of the client system and the server system on the VM.
