Abstract
A method for indexing virtual machine version snapshots in a virtualization environment commences upon receiving a request (e.g., from an administrator or agent) to initiate a virtual machine version snapshot operation on a subject virtual machine. Processes within or controlled by the subject virtual machine are requested to temporarily suspend transactions and file I/O. When the processes that have been requested to temporarily suspend transactions and file I/O acknowledge quiescence, the method continues by generating a virtual machine version snapshot data structure. An entry in an index is formed from the virtual machine version snapshot data structure. Multiple instances of virtual machine version snapshot data structures can be stored in the index, and the index can be queried to determine the state that a virtual machine had at any of the snapshotted moments in time.
