It’s on the FAQ page: “Can I automatically install change block tracking on all my clients?” You can disable CBT on the advanced settings page. With 2.1.x you can also create a group where it is disabled.
so you mean I need to install/update CBT-client for all the clients, and disable the function for the client don’t need it?
will the cbt kernel driver be installed for these clients with cbt function disabled?
and about winxp, is “Perform autoupdates silently” enough to prevent the client trying update to 2.x?
it will be clear if I can update both client for their specific versions. but I will do what it the best method for now.
