Hmm we never received that email but I found out about it last week on another Thread here.
I requested more info on August 14 via their form but haven't received call or email so I guess its not for us.
It sounds very appealing because of the incremental backup but I have little confidence in AC's new offerings (i.e. tried using ACPM and it failed, v8.2.4 seems unstable, etc.)
Are they actually Beta testing it?
