plugin to copy pages

Can you recommend a plugin to copy pages? The one I used with the last enfold theme (it is called “duplicate post” from Enrico Battocchi) asks for FTP access data. I don’t know why it is requested but of course I don’t want to post my private data. I already used the plugin for the enfold theme some time ago and I did’t get the question about the FTP access data. Can you recommend another plugin with the same fuctions? I need it to duplicate sites to save the old versions.
