At least for the sysvol folder you should know, that the tar command from the 
script doesn't backup the filesystem extended ACLs. If your tar command 
supports '--xattrs', you should add to the tar command(s) in the script to 
include the ext. ACLs. If your version of tar doesn't support this, maybe you 
can use star.
