How to make a backup copy in blockchain.info wallet on Google Drive?
Previously, under the old design was there such a function,and i use her, where is she now,
I'd guess that you're talking about the beta version. AFAIK, the beta version doesn't have such feature(function) {not sure}.
how can i make backup?
There's an other backup option that you should(can) go for(try out).
