Dont buy this plugin. I have bought it for a client of my company and try to backup everything for migration to a new website. It give an error. After i ask for support the author dont know the problem (email support 23 okt 2018).
Now on 1 november 2018 i still not have any replay of the author, i dont hear anything of him.
I have found the problem myself, the plugin has not a backup folder. I had to create this myself. The backup problem was solved but by import the backup into the new website, it gave another error that the form was not created succesvolly.
Too many errors and bad support communication. After 10 days still no response...
