HA / DR / Replication relationships

Working out the companies existing HA and DR procedures is vital.

I find the best way to do this is to map them out in something like visio, Its important to look at this on a database level not server, as no all will go to the same server.

First thing is to get an idea of any Mirrors, AG's or Log shipping.

I recommend that there are mapped in Visio with a different colour line per HA type.

The same can be done with Replication.
