  • Bonjour ludoo,

    Tu trouveras plus d’information sur  SIS dans le document : http://download.microsoft.com/download/8/a/e/8ae7f07d-b888-4b17-84c3-e5a1976f406c/SingleInstanceStorage.doc

    Storage Filter Architecture

    The SIS Storage Filter is a kernel-level file system filter driver that manages the duplicate copies of files on hard disk volumes, as identified by the SIS Groveler. The SIS Storage Filter copies one instance of the duplicate file to the SIS Common Store, and replaces the files with a link to the SIS Common Store copy to improve disk usage.

    The SIS Storage Filter helps ensure that users see appropriate behavior when they access SIS links. When an application tries to open the original file, the Storage Filter redirects any file input or output to the SIS file in the SIS Common Store directory. The filter driver is in all input/output (I/O) paths of volumes to which it is attached, and handles the normal file operations that happen on SIS links, such as read, write, open, close, and delete.

    Creating SIS Links

    The SIS Storage Filter creates SIS links. SIS links do not contain any file data, but just contain a pointer to the Common Store file. Common Store files are located in a protected directory. Because the data for SIS files is located in the Common Store rather than in any particular link file, SIS avoids the problems that would arise when a linked file is deleted or overwritten.

    If the source file is not already an SIS link, its contents are copied to a newly created file in the Common Store, and the source file is converted into a link to that Common Store file. The destination file is then also updated as a link to the Common Store file (either pre-existing or newly created). SIS keeps some out of band information (called backpointers) associated with the Common Store file that contains the set of links that point to the Common Store file. A COPYFILE request adds such a backpointer for the destination, and also for the source if it was not already an SIS link. (Applications may use COPYFILE to create an SIS link. If the file is already a merged duplicate, only a link is created. If the file exists elsewhere as a single copy, SIS merges it as well.)
