Etcd backup and restore commands

I am following the mock exam 2 and it seems that the video with solutions for etcd backup is not valid anymore since the etcd.yaml is quite different - am I supposed to copy all those parameters to have the backup ?

Hi <@UL6U8C65R>,

Please have a look at for the parameters that we need to remember for etcd backup and restore.

ETCDCTL_API=3 etcdctl --help is the best source for any help for reference and as well as in exam.

thanks <@UGZ01D3MW>!
