I post too Much on Here!!

When I mentioned doing this a while back in the context of the R3 (if the slower SD card limits my shooting speed in writing RAW to both cards, I planned to write only to the CFe then copy images to the SD during down time), it was also met with surprise by some.Dead easy: Go to the blue menu (the play sign one, 3rd along), page 1 bottom Copy Image. It will give the instructions for copy from card 1 to card 2.
Glad the the suggestion was helpful.
No disrespect to @Felix intended, but it’s surprising to me that people don’t RTFM.
