Akibu,
The convention is to not use the trailing "/" on rsync share names. Unlike most linux utilities, in certain cases rsync will behave differently whether or not there is a trailing "/" on a directory name.
So you probably want do this:
$Conf{RsyncShareName} = "/cygdrive/j";
$Conf{BackupFilesExclude} = {
Also, if the list of directories to include is shorter than the list to exclude, you might be better off using $Conf{BackupFilesOnly} to list the directories you want. That way if you make a mistake, it's likely the backup is smaller (or empty), which makes debugging and iterating easier.
