Hi there! About the errors you get:
- it's good that you excluded the _vti_pvt dir, that has some system files that you don't need to move and the clone generator can't access
- the cloning/move error is different than the generated backup error
- regarded to this error "FTP upload has failed for file /home/wetlock/public_html/administrator/components/com_cloner/Joomla.Cloner.php" , try to check the ftp path to which you want to move the clone, see if it's correct and if you can upload files through ftp in it
If you still have problems moving the clone open a ticket here
http://www.joomlaplug.com/component/option,com_waticketsystem/Itemid,43/ and send me your Joomla details and the ftp details to where you want to move the clone!
