My pi3 is placed 300+ kilometers away and I can't reach it frequently(probably 2 times a year).
I would like to backup the disk image remotely once a month, almost all tutorials I found are for which could hold it in hand.
I have a macbook and windows desktop(putty/winscp ready, but I need diskimage backup), is there a way for me to do that remotely?
I have working openvpn between pi and my local PCs.
