Abstract

Facility for providing backup and restore of all data center components including physical machines, virtual machines, routers, networks, sub-networks, switches, firewall, directory lookup, DNS, DHCP and internet access. Virtual or physical machines are associated to data center components and a software defined network, storage, and compute infrastructure is provided.

Claims

1. A method for virtualizing a plurality of computers in a data center, the computers being connected to a network having a network topology, the method comprising:

creating a backup image of each of the computers;

saving together with each backup image, supplemental to each backup image, configuration information of the corresponding computer, the configuration information comprising persistent and volatile state;

creating each backup image as a snapshot of the corresponding computer, the snapshot comprising an application-consistent image as of a specific point in time of primary storage of the computer;

saving together with the configuration information saved with the backup image, information representing the state of the network connections of the computer;

loading the backup images as a cloud computing node; and

loading the saved information regarding network connections together with the backup images, and using such information to recreate the network connections of each such computer.

2. The method of claim 1, further comprising:

collecting by a metadata collection agent the configuration information.

3. The method of claim 2, wherein the metadata collection agent is resident on one of the computers.

4. The method of claim 1, further comprising:

collecting the configuration information by a plurality of metadata collection agents.

5. The method of claim 4, wherein each of the plurality of metadata collection agents is resident on one of the computers.

6. The method of claim 2, wherein the configuration information comprises network configuration of the data center.

7. The method of claim 6, wherein the network configuration comprises router configuration information, switch configuration information, or network topology information.

8. The method of claim 1, further comprising:

creating a software defined network.

9. The method of claim 8, wherein creating a software defined network comprises:

generating a cloud deployment template.

10. The method of claim 1, further comprising:

probing the network to determine a firewall configuration.
