摘要
Disclosed are techniques for using known update technologies to automatically identify the updates installed on a physical machine prior to facsimile creation, to locate the update packages from an update server, and to download them to the machine performing the facsimile creation. The use of update technologies enables precise identification of the updates that affect the defined set of files requiring replacement, and thus minimizes the number of updates that need to be downloaded. In addition, the desired set of replacement files are extracted and cached to allow for their reuse during subsequent facsimile creations using either the same or different physical or virtual machine as the source. Downloading the minimal set of updates and caching them for reuse eliminates the redundant downloads of updates and results in a shorter time for facsimile creation.
