For Setup 1, both the System as well as the Data disks are replicated. This type of configuration has its advantages as well as disadvantages as shown in the table below:

Type of setup	Advantages	Disadvantages
Setup 1: Replicating the System as well as Data disks	Since system drive is replicated, all system settings and changes are replicated to the Secondary site. Thus, the Secondary site is an exact replica of the Primary site.	If the guest image on the Primary is corrupted due to a crash, then the guest image which is replicated to the Secondary may not boot or start. The application on the system drive generates huge I/O on the system drive, which when replicated adds to network traffic. During migrate and snapback operations (resync from replica), users may encounter "fail to acquire lock on volumes" error. This happens due to open handles on the volume.
