Writing Duplicate Data to 2nd SD card

new user here...  new arduino well.  trying write program test apparatus work. need write data 2 sd cards. 1 removed , transferred while other stays on board emergency backup. have far, know doing cs pins way wrong, cant find on how alternate them. of code had removed length. advice...

sdclass sd2;
sdclass *sdcard = &sd;

this won't work sd.h.  sd.h wrapper 5 year old version of sdfat supports 1 card.

this version of sdfat supports multiple cards.

see twocard example.

the threecards example uses software spi 1 card , hardware spi other cards.

this version of sdfat can configured multiple cards recommend beta since version no longer supported.
