This snapshot features are supported in a virtual environment to create multiple snapshot copies of each volume, and copies of these time points allocated to other virtual machines. So users only need to create a snapshot copy of production data and assigned to the virtual machine specifically for testing, we can create a powerful test environment. Once the user create a virtual server environment, users can quickly create a virtual test server. Testers can not only within a few seconds to obtain the true distribution of the "real time" data, but also in the whole testing process for data snapshot.
