Thanks for your reply.
I am using Norton GHOST 15 to save Folders and Personnal Data's, but incremental recovery point of recent changes is not as flexible as can be a soft to replicate specific user files.
I had trouble with SyncToy. While installing, synctoy hangup (not respond) and I had to install first Sync Framework 2.0 and then again Synctoy to make it work.
But somme issue right next tell's me to do not trust to much on it ! This is a personnal point of view of course.
I do not know, how exaclty SyncToy must be installed as there is no info why I have to install first Sync Framework 2.0, as SyncToy already get this on the package. Download details: SyncToy 2.1
If I may wrong, do not hesitate to tell me.
I will look at Mirror Folder anyway.
