Abstract
A survey tool for use in a Recover to Cloud (R2C) replication service environment that determines configuration information automatically (such as through SNMP messaging or custom APIs) and stores it in a survey database. A Virtual Data Center (VDC) representation is then instantiated from the survey database, with the VDC being a virtual replica of the production environment including dormant Virtual Machine (VM) definition files, applications, storage requirements, VLANs firewalls, and the like. The survey tool determines the order in which the replicas are brought on line to ensure orderly recovery, by determining the order in which each machine makes requests for connections to other machines.
