Archiving virtual machines in a data storage system

Abstract

The data storage system according to certain aspects can manage the archiving of virtual machines to (and restoring of virtual machines from) secondary storage. The system can determine whether to archive virtual machines based on usage data or information. The usage information may include storage usage, CPU usage, memory usage, network usage, events defined by a virtual machine software or application, etc. The system may archive virtual machines that are determined to have a low level of utilization. For example, a virtual machine can be archived when its usage level falls below a threshold level. The system may create a virtual machine placeholder for an archived virtual machine, which may be a “light” or minimal version of the virtual machine that acts as if it is the actual virtual machine. By using a virtual machine placeholder, a virtual machine may appear to be active and selectable by the user.
