US Patent 11379322 Scaling single file snapshot performance across clustered system

In some embodiments, a process for restoring a version of a virtual machine using a data storage system comprises identifying a particular version of a virtual machine to be restored, determining a base image from which the particular version may be derived, determining a set of incremental files for generating the particular version, generating a file associated with the particular version using the base image and the set of incremental files, and outputting at least a portion of the file.
