I am having a hard time figuring out exactly how to run rsync to get it to do what I need it to do.  Basically what I need is as follows given a single source folder with multiple sub-directories:-If files for a given subdirectory are changed in the source folder, sync those changes to the destination (update files and delete files not found in the source folder any longer).-If a folder is found in the source but not the destination, sync the folder and all of its contents to the destination.-If a folder is found in the destination but not in the source, do nothing (e.g. don't delete it).This is what the directory structure would look like:Source Folder   Folder 1      File 1 unchanged.txt   Folder 2      File 2 newer.txt   Folder 3      File 3.txtDestination Folder   Folder 1      File 1 unchanged.txt   Folder 2      File 2 old.txt (to be replaced with File 2 newer.txt)   (Folder 3 not yet in destination, to be added from source)   Folder X (not in source, to be left untouched)
Can rsync be configured to avoid modifying subdirectories not found in the source folder?
