For such a great backup it has really bad licensing functionality. Even if I purchase the EnterPrise version with unlimited licenses, I need to be cautious as if I install it on a client site and the client moves the site away from me, I have no way to deactivate it.
I use so many plugins that have license keys that are centrally managed – if my client takes it, I can simply deactivate the site.
Seems like Updraft is living in the past.
