One awesome service I’ve found recently is the ManageWP one – service that allows you to manage all your WP sites through one dashboard only.
Since we’ve found it we no longer use the BackupBuddy plugin (except for some specific cases of course). However ManageWP let us clone our installs and do fresh installations for demos and testing and many more.
It’s free for up to 3 websites and some symbolical price for more websites. Our testing department is really grateful for that chance now.
