Keeping a backup of icloud contacts
I have icloud working fine with all my contacts but realised that I have no backup of my contacts should icloud screw up and lose them so I have greated a new gmail account ( which has no contacts in it ) and want to duplicate my icloud contacts in gmail. Under info>contacts in itunes if I select google contacts as the sync provider I get a scary message that puts me off going any further for fear of losing all my contacts. All the posts I've read so far are concerned with moving from gmail to icloud which is not what I want to do.
Can anyone step me through it please?
thanks in advance
