i'm uncomfortable that it's hung but i don't have 2.1.4 as i'm a fairly recent purchaser and i only have 2.5. i don't have the option to leave it running unchecked and i've had to stop it...

pressing Stop gets me the 'Stopping now will leave backup in an unknown state. Are you sure you want to stop?' message but I've had to just do it. is there any particular recommended process to make another copy? can I try again to the same location? will it just happen again?
