Hi All

I've just received notification on my Galaxy 10.1 tablet that an update is ready to be downloaded/installed.  I've deferred it for the time being (for a day) so I could research this a bit, as I've read a few horror stories about updates causing problems. 

Could you please advise me about how to back up and then restore my music, photos, downloaded programs, etc?  I assume I have to do that, or I will lose the lot.

I'm sorry to appear such a klutz, but I'm just not sure how to go about this safely.  I have Kies on my computer, but that hasn't always worked that well.  I assume this is an OTA update though, right?

Thanks so much in advance.
