Morning, the backup is still in progress, done 4.32GB of 20.35GB having been 
running all night. Exceedingly slow but I will leave it be. It has also said 
since last night "Calculating time remaining....".

I would have connected it via Ethernet to the TC to accelerate the process, but 
I've had no luck for years of trying to get the Thunderbolt to Ethernet adaptor 
working. That's another story I won't bring into this thread.

I suppose you're looking forward to the Pies V Bombers on Anzac day Ronnie. 

Regards


Pete
