Abstract
A virtual machine container file is analyzed to determine which portion of the virtual machine container file corresponds to a virtual machine file system metadata of the virtual machine container file. One or more differences between a first version of a virtual machine container file and a second version of the virtual machine container file are determined at least in part by traversing a snapshot structure associated with the virtual machine container file. The determined one or more differences that corresponds to the virtual machine file system metadata portion of the virtual machine container file are identified based at least in part on the analysis of the virtual machine container file. The identified one or more differences corresponding to the virtual machine file system metadata portion of the virtual machine file are utilized to identify one or more changes from the content files included in the first version of the virtual machine container file to content files included in the second version of the virtual machine container file.
