Windows Server 2012 -- HyperV "replicatation" strategy ?

Below shows my Current and Desired setups.

What HyperV "replicatation" websites show how
to do the below "Desired Setup" #2 a and b
since I am trying to find out which option I want,
but I also want to keep 7+ days of nightly backups
so I can restore if someone deletes a file and fails
to tell me until days later ?
----------------------------------------------------
Current Setup
 1. two old EqualLogic SANs
      ** one at each location
 2. two old VMWare servers, switching to HyperV
      ** one at each location
 3. two old Windows 2003 servers
      ** one at each location
 4. nightly replication between SANs
      ** if one fails I can restore from another
----------------------------------------------------
Desired Setup
 1. two new Windows 2012 servers
      ** one at each location
 2. use "Windows 2012" built-in HyperV replication
      ** replicate file and file level security
         ever 5 minutes to one of the below
            a) on-site
                 ** on standby server
                 ** on a SAN
            b) off-site
                 ** other site I have, on standby server
                 ** other site I have, on a SAN
                 ** via cloud, on standby server
                 ** via cloud, on a SAN
