I pay amazon s3 for backup, so by using this backup plugin, it is asking me to pay an additional .50 for site. So can you please explain this. I really don’t need to be paying double for backing up one site. thanks.
You logged in into WPAdm Online Service. The plugin is fully free and to backup you do not have to pay anything. You can pay in case ONLY if your want to manage several websites from one place and use some additional features. If you need none, do not pay.
