You need to use mongo & with tarmk not available.
I dont think there are any integration done between AEM and backbase.One
need to do a feasibility study and depends on how Backbase exposes its
services for personalization. You can raise a ticket for the same and
see if Adobe has anything for this.
Assuming you are asking for tree activation for details look .
Basically iterates through all the nodes, adopt to page & assets to get
lastmodified date and also get replicationstatus. 
As per my understanding, to use Adobe Campaign we need to integrate it
with AEM for AEM based application. But we have scenario where we need
to know if we can directly integrate Adobe Campaign with 3rd party
framework (Backbase) without AEM. Please let me know if it is possible?
